PRODUCT FAQS

Our Bulb Finder and Bulb Size Guide is a great place to start! We receive the information for our filter and bulb model guides straight from market research and vehicle databases. We always recommend that you consult your vehicle's Owner's Manual or check the bulb currently installed before purchasing a new bulb. Once you have confirmed the bulb size, select the appropriate bulb range according to the required wattage, brightness, and color temperature.

If in doubt, feel free to contact our customer service staff to help you find and recommend the right product.

If it is a newer model year or a special model, we have not yet confirmed that your vehicle is suitable for our products. You can obtain bulb sizes from your owner’s manual or if you would like to remove the bulbs you are trying to replace, you can send us pictures of the bulbs in question and we can help identify them visually. Once you know what size bulb you need, you can order by size directly from our “By Bulb Sizes” navigation bar!

Traffic regulations require that the front end of the vehicle be illuminated in the colors of white or amber, and the rear end of the vehicle be illuminated in the colors of amber yellow or red. When choosing an LED bulb color you also need to match the color of the lens that covers the bulb.

• If the lens is clear, use an LED color that complies with regulations (e.g., white for headlights, amber for turn signals).
• If the lens is red (e.g., brake lights, tail lights), use red LEDs or white LEDs (which will appear red through the lens).
• If the lens is amber, （e.g., some front turn signals, use amber LEDs or white LEDs (which will appear amber through the lens).

Incandescent bulbs are designed with standardized electrical connections, with a single function and a unique model number. Each model corresponds to a unique interface and function, which cannot be technically extended for adaptability and therefore needs to be strictly differentiated.

LED bulbs, on the other hand, are more technically flexible, and LED bulbs with the same physical interface can be adapted to multiple functions by means of driver circuits. For example, an LED bulb may be compatible with 3156 and 3157 two interfaces, through the internal circuit to switch the function mode.

For this reason, product pages are labeled with multiple models to clarify the range of adaptations.

The headlight products in the Bulb Finder are marked as “Off-Road Use” because they have not been tested in all vehicles. This does not mean that these bulbs will underperform. In many cases, it will outperform a traditional incandescent bulb. However, we cannot guarantee that LED bulbs will comply with the regulations on all roads.

A dual-filament bulb provides two levels of light intensity: low and high. For example, a tail light emits low-intensity light, while a brake light emits high-intensity light.

CK/SRCK and standard configurations are two types of dual-filament sockets (e.g., 3157 & 7443) used in turn signal applications. Incorrectly installed LED bulbs can cause circuit shorts. Verify your vehicle's socket type with your local dealer or using a test lamp.

We always suggest replacing headlights in pairs, because it’s a really good idea for a couple of reasons. Typically, headlight bulbs are the same age, so when it's time to replace one, it's time to replace both. Over time, the performance or brightness of headlights decreases (light fade), so if you replace only one bulb, you're likely to end up with one bright headlight and one dimmer one which can impact your downroad visibility and your field of view while driving.

Both headlight assemblies and taillight assemblies typically contain bulbs, but if the assembly does not come with pre-installed bulbs or needs to be replaced separately, the bulb needs to be selected based on the bulb sizes supported by the assembly.

If the assembly is being replaced with an OEM part, the bulb model required is usually the same as the original. If the assembly is a retrofit assembly, a specific bulb model may be required, and you need to check the assembly manual or product information to clarify the bulb model (e.g., H1, H7, H4, etc.).

We offer LED replacement bulbs for most automotive applications, including interior lights, license plate lights, directional lights, brake lights and fog lights. Most AUXITO LED bulbs are designed to be CANbus error-free , with built-in circuitry or decoders to prevent electromagnetic interference (EMI) generated by the LED driver circuitry from affecting vehicle CANbus communications. And some bulbs are not error-free. Please check the product page for specific information.

CANBUS Anti-flicker decoders are commonly used to solve flicker problems that occur when LED bulbs are installed in a vehicle. Purchasing a CANbus anti-flicker decoder depends on several factors:

1. Some vehicles have sensitive CANbus systems (e.g. Jeep, Ram, Chevy lights) and will give a bulb out warning when installing aftermarket lighting bulbs. If your vehicle is of this type, purchasing a CANbus anti-flicker decoder at the time of purchasing your LED bulbs may be a solution.

2. LED bulb types: Some of our store's LED bulbs have been designed with CANbus compatibility themselves to avoid flicker issues. When purchasing LED bulbs, you can avoid the need to purchase additional decoders by choosing bulbs with CANBUS compatibility.

3. Flicker Severity: If you have installed LED bulbs that are already experiencing severe flicker problems that affect normal use or driving safety, purchasing a CANBUS anti-flicker decoder may be an option worth considering."

Sometimes vehicle manufacturers make parts changes in the middle of production. Unfortunately, those changes are not always made available to us. We always suggest consulting your vehicle's owner's manual or checking the bulb that is currently installed to verify part numbers. However, in the event of a part number mismatch, our customer service staff will help you and give a satisfactory solution.

Yes. Installation instructions for the product are included in our box. Please contact us if you encounter any other installation problems.

Although most LED bulbs are sized 1:1 to the original halogen bulb, some bulbs are equipped with a fan at the end to dissipate heat for optimal bulb operation in order to increase brightness. Some car models have a compact mounting space and it is not possible to put the dust cover on after installing the LED bulb. We recommend checking the installation space and checking the bulb size on the product page before purchasing to select the right lighting product.

Since the starting current of LED bulbs is significantly lower than that of conventional halogen bulbs, it may lead to residual current in the original vehicle circuit, and the this residual current can cause flickering.

The vehicle ECU determines bulb status by monitoring circuit resistance, which is typically lower for LED bulbs and can trigger the system to falsely indicate a “bulb fault”, resulting in a dashboard error.

Installing a decoder can usually solve this problem.

Here are some possible reasons:

1. Power Problem: LED bulbs usually need a stable power supply. If the power supply voltage is unstable or there is a short circuit problem, it may cause the LED bulb to go out suddenly. You can try to install a decoder to solve the problem.

2. Overheat protection: Some LED bulbs have overheat protection that automatically shuts off when the bulb gets too hot to prevent damage. This may be caused by the bulb being installed without good heat dissipation or the surrounding environment being too hot. It is recommended to make sure that there is enough space around the lamp to dissipate heat and avoid installing it in a confined environment. Also, reduce the usage time of continuous LED bulbs.

If you have just installed the product and find that one of the bulbs does not work there are possible reasons that the LED bulb is not securely seated into the lamp holder or the contact piece is not aligned, resulting in poor contact or bulb damage.

Here are our suggested solutions:

Reinstall the bulb by screwing the bulb fully into the lamp holder, making sure that it makes tight contact with the bottom metal contact. If the bulb is still bad, try switching positions. Test if the problem is with the bulb itself by switching the poorly lit bulb to another lamp holder in the same fixture.

If the bulb is the problem, contact customer service for replacement.

Glare can be caused by several factors, including improperly installed LED bulbs, improperly aimed headlights, aged-hazy headlight lenses, non-compliant unsafe upgrades, or a combination of all the above. AUXITO LED bulb sizes are designed according to OEM standards and quality tested to eliminate dangerous glare by properly installing them and focusing the light where you need it on the road, not on oncoming traffic.

If you experience glare after installing an LED bulb, it is recommended that you check the installation to ensure that the bulb is compatible with your vehicle and consult a professional to adjust the headlight alignment if necessary.

Properly aimed headlights provide optimal visibility and eliminate dangerous glare for other drivers on the road. Click this blog for helpful information on how to aim your headlights.

Please select the appropriate jump starter for your vehicle type and engine size.

Motorcycles/Small Engines (e.g., lawnmowers, ATVs):

A 300–400A jump starter is sufficient due to their smaller battery and lower power demands.

Compact Cars (4-cylinder engines):

Opt for 400–600A to handle moderate cranking needs.

Mid-Sized Vehicles (V6 engines):

Choose 600–1000A for reliable starts, especially in colder climates.

Large Vehicles (V8 engines, trucks, SUVs):

Prioritize 1000–2000A to ensure enough power for high-compression engines.

Diesel Engines: Require 2000A+ due to higher compression ratios and energy demands.

Step 1: Connect the jumper cable clamps to the battery terminals (first connect red to the positive terminal, then black to the negative terminal)

Step 2: Connect the jumper cables to the jump starter

Step 3: Wait for the green LED on the jumper cables to light up, and then start the vehicle

Step 4: Disconnect the jumper cables from the starter and the battery.

First check for connection errors and make sure the indicator light is on properly. If the starter light is not in a constant green state, the starter may not be properly connected to the positive and negative terminals of the vehicle's battery, or the clips are not making good contact (e.g., oxidized or loose clips).

If your vehicle does not start even after using a fully charged jump starter and connecting it properly, the battery may be completely dead or damaged, or there may be a problem with the starter, alternator, or other system. You can try a self-test based on the ‘Car Won't Start?’ article or take your vehicle to an auto body store to have it checked.

No. A portable jump starter is not designed to fully charge a dead battery, it can provide a temporary boost to start your engine. Jump starters have small internal batteries (e.g., 10,000–20,000 mAh) optimized for power output, not sustained charging. They lack the voltage regulation and slow-charging circuitry needed to safely charge a depleted battery. Prolonged use as a charger may overheat the jump starter’s battery or damage its internal components.

AUXITO jump starter power supplies are equipped with a battery level indicator (LED light or digital display) to show the current level. Check the indicator for the remaining charge.

We recommend charging the jump starter when it is less than 50% charged to ensure that there is sufficient power to start the vehicle. Also, to maintain optimal performance of the lithium-ion battery, we recommend charging the starter every 3 months.

Using a jump starter while it's plugged in can be risky and is generally not recommended.

Jump starters typically use lead-acid or lithium batteries. If the internal battery is completely dead, plugging it in may not immediately restore functionality. Therefore most portable jump starters are designed to be charged fully before use to provide a consistent amount of power before use.

For most passenger cars, a 600–1000A jump starter with 12V compatibility is a safe choice. If you own multiple vehicles or a diesel engine, invest in a 2000A+ heavy-duty unit.

Consideration of usage scenarios, functional requirements, and product features. The following are the core recommendations for different needs in the process of selecting an inflator pump.

Wireless (battery-powered): Highly portable, suitable for outdoor or no power supply scenarios.

Inflating capacity

Maximum PSI: 30-35 PSI for regular cars, higher (e.g., 150 PSI) for trucks or SUVs.

Inflation speed: High-power or dual-cylinder motor can shorten the time.

Portability & Range

Size & Weight: Lightweight design is suitable for daily carrying.

Endurance: Battery capacity determines continuous use time.

Additional features

Auto shut-off and preset mode

Multi-function adapter: Compatible with cars, bicycles, balls, etc.

Emergency lighting/SOS function.

Using a portable tire inflator is a straightforward process. We recommend following these steps.

Prepare the inflator: Make sure that the inflator is fully charged or can be connected to a 12V power source. Securely connect the hose and the inflator.

Check the tire pressure and confirm the recommended value: Usually, portable inflators can display the real-time tire pressure. You can find the recommended tire pressure for your vehicle in the owner's manual or on a sticker located on the driver's side door jamb.

Connecting the inflator: Connect the inflator to the tire valve, making sure it is tight.

Setting the desired tire pressure: select the air pressure unit and set the target pressure.

Check Pressure Again: After inflation, you can use the tire pressure gauge to recheck the tire pressure to ensure that it matches the recommended level.

We recommend checking your tire pressure once a month to ensure that your tires remain within the recommended pressure range. It is also a good idea to check the air pressure before a long drive or during drastic temperature changes.

Yes, we sell portable inflators packaged with additional attachments that can be used to inflate other items such as bicycle tires, balls, etc.

It is generally safe to leave a portable tire inflator in your vehicle, but to ensure optimal performance and longevity, keep the inflator in a dry place and avoid leaving it in direct sunlight or extreme cold for long periods of time.

No, the 7in off-road lights we currently sell do not come with a wiring harness, but do come with a DT connector in the package.

This will depend on your off-road driving. If you frequently drive on twisty mountain trails or in wooded areas, you may need more focused, long-range lighting; while in plains or desert areas where extensive lighting is required, flood beams may be more appropriate.

Meanwhile, flood beams are best suited for low-speed driving and can improve roadside visibility. Spot beams are best suited for high-speed driving and can improve roadside visibility.

The AUXITO 7in Off-Road Light offers both spot and flood modes that you can switch between at any time depending on the road conditions.
