What is an LED?
An LED is a light emitting diode that is used in a variety of applications as a source of light. When a suitable voltage is applied on to the two leads of a light emitting diode, it creates an effect known as “electroluminescence” which will result in a light source that is integrated on our products
How do I know how bright these LED bulbs are?
In the automotive industry, the brightness of an LED bulb is usually categorized by “luminous flux”(lumens) which is the unit of measurement of light that is visible to the human eye. You should review the lumen rating to determine the total visible light output of the LED lamp.
What is color temperature and how do I match my headlamps with my fog lights?
Color temperature refers to the color of the light emitted from the lamps. The temperature of the light will determine the color of the light. The color temperature is measured in kelvins(K) and should be considered when trying to purchase a specific color of LED lamps.
What are CK/SRCK and standard configuration and why should I check my sockets?
Standard and CK/SRCK are two types of dual-filament(3157 & 7443) sockets for turn signal applications. The ground terminals and leads are located in a different position and may cause a short on the circuit if the proper LED bulb is not installed. You should contact your vehicles local dealer or test the sockets(using a test lamp) to determine what your vehicle is equipped with.
What is a dual-filament bulb?
A dual-filament bulb is a lamp that supports to levels of light intensities; low and high intensity. A good example will be a tail and brake light setup. Tail light is the low-intensity filament and brake light would be the high-intensity filament.
What bulb size should I use?
The bulb size that should be used depends on the original bulb installed, or what the vehicle’s owner’s manual indicates for the application you are working on. Most cases, you can easily identify the bulb size by simply consulting the owners manual. You may also compare the factory bulb to our product to determine if it is a suitable replacement size.
What color LED bulb should I use?
The color of the bulb should ALWAYS be within the legal limits of the laws of the road when operating an automotive vehicle. You should go based on the part number on the bulb or even check the vehicles owners manual. The manual and factory bulb will, usually, have a part number which indicates the type of filament bulb, bulb size and color(white, amber, or red). (Ex. 7444NA, & 3157A / NA=Natural A=Amber) You should also consider the color of the lens on the housing assembly. For safety, the color of the LED bulb should correspond to the color of the lens so that the color is vivid and noticeable to other drivers. If the lens is clear, you should follow what the manual.
Why is my bulb flickering/dimming as soon as I install them and turn them on?
Some vehicles are equipped with a computer system that will monitor your vehicles lighting applications. They are designed to notify a driver of problem or fault with the functionality of a lamp. The system may recognize the low power draw of your LED bulb as a problem or fault. It may cause a lamp out indicator on your dashboard and sometimes cause the lamp to flicker or dim because it is recognizing the lamp as an open circuit(faulty/burned bulb). A load resistor or decoder should be installed by tapping onto the ground and lead wires of the socket. These components will ‘trick’ the computer system(CAN bus, BCM, etc. )into believing that you have a functioning bulb installed.
Why is my turn signal flashing faster than normal?
This is a very common malfunction with turn signal applications when upgrading to LED. The issue is known as “hyper-flashing”. Hyper-flashing occurs when the flasher relay(controls rate of flashing on the turn signals) cannot detect the power going to the turn signal. Since LED bulbs are more efficient, there is a substantial decrease in power draw. A load resistor should be installed on to the lead(turn signal) and ground wires. Load resistors will simulate a power draw that resembles your factory halogen bulbs(20W-27W) to normalize the rate of flashing with your LED bulbs. Another option, if possible, is to upgrade the factory flasher relay module with an electronic LED flasher relay which will work with a low power draw. Factory equipped ‘thermal flasher relays’ cannot be upgraded to the proper load should be applied to the sockets using resistors.
What should I do if my LED bulbs do not fit?
This depends on the type of fitment issue you are experiencing. You should consult your owners manual to confirm the size or part number. The manual has information that your vehicle's manufacturer has included and is more reliable than any other source, guide or reference available online. You may also contact your local dealer to request the information. If there is minimal labor involved, checking the factory bulb, and comparing it to the LED bulb you are trying to install is the best method to confirm that the bulb size(and dimensions) are accurate and suitable for your vehicle. Once you have determined the reason for the fitment issue, you should install an LED bulb based on the information you have learned.
What is an LED ‘switchback’ bulb?
An LED switchback(3030, PX, and EX series) bulb is like every other dual-filament LED bulb, but instead, support two filaments that have two different colors(Usually amber and white) for each filament rather than having the same color with two light intensities. Our LED switchback bulbs will use white for the low-intensity filament, and amber for turn signals. For most vehicles, you will have a white color for parking/daytime running lights, and amber for the turn signal application.
What is an error-free LED bulb?
An error-free LED bulb is an LED lamp that is CAN bus-ready. This means that the bulb is equipped with either resistor (3W-5W) to simulate a larger power draw, or have built-in decoders(LED headlights) to increase starting amperage both of which the vehicles computer system(CAN bus, BCM, etc.) should detect. This will ensure that the computer system does not recognize the lamp is a fault or an open circuit due to the low power draw and will prevent minor malfunctions such as a lamp out indicator and even other common malfunctions that a CAN bus or similar system may cause.
How do I make the lamp out indicator go away?
A lamp out indicator may come up with an LED bulb depending on the vehicle and whether or not the vehicle is equipped with a CAN bus or similar computer system. An error code may be triggered if your vehicle cannot detect the LED bulb that is installed on the socket. A load resistor or decoder should be installed to the lamp that is causing the error code. These components will ‘trick’ the computer system into believing you have a functioning “halogen” bulb installed rather than a low power draw LED lamp and thus correct the malfunction.
How do I check which LED bulb should be installed on my vehicle?
This depends on the type of vehicle whether American, European, Japanese, and/or Korean. The bulb you choose should be based off the factory bulb and/or owners manual. European and American vehicles may require certain types of LED bulbs that offer error-free capabilities for vehicles like GM, Ford, Jeep, Chevrolet, as well as Audi, BMW, Mercedes-Benz, Jetta, Mini, Porsche etc. You then need to consider the features/hardware of the LED bulbs to determine if they are a suitable replacement for the application you are upgrading. The last factor that will help determine the right LED bulbs is the color and light output. The owners manual and color of the lens should determine the correct color of the LED bulb.
WHAT ARE CAN BUS LEDS BULBS?
CAN Bus LED bulbs are simple plug-and-play LED bulbs which are made specifically for CAN Bus-equipped vehicles? These bulbs work with your vehicle’s advanced computer system, so when your vehicle’s computer reads them, they respond back correctly.
What does CAN Bus mean?
CAN Bus means Controller Area Network Bus. This system monitors your vehicle and reports operating conditions. CAN Bus systems are commonly found in European vehicles such as BMW, Audi, Mercedes, Volkswagen, Porsche, and many American vehicles. While most late model American vehicles have CAN Bus systems, it is always good to check with your vehicle dealer to see which system your vehicle has before purchasing electrical products.
Will CAN Bus LED Bulbs Prevent “Bulb-Out” Indication?
Each vehicle has different requirements that the CAN Bus system is looking for, but in most cases CAN Bus LED bulbs should prevent a “bulb out” indication in areas such as the tail, brake, and running lights. If you use a standard LED bulb that is not a CAN Bus application, you would consistently get a “bulb out” dashboard indicator because your system can’t communicate with a standard LED bulb.
Will CAN Bus LED Bulbs Prevent Hyper-Flashing?
CAN Bus bulbs will not prevent hyper-flashing of turn signals. These bulbs are communicating with the CAN Bus system, but the relay still needs an appropriate amount of load to operate correctly. Your electrical system could require load resistors or an electronic flashing relay to stop hyper-flashing. The factory relay causes the hyper-flash when it thinks there is not a bulb working.
Can you use CAN Bus LED bulbs in non-CAN Bus applications?
Yes, the can-bus led bulb can be used as non-Can Bus application.
I have error free bulbs, but they still throw an error, why?
- Take out the LED bulb and replace it with the stock bulb, turn on the vehicle, and confirm if the error message is cleared.
- Turn off the vehicle and re-install the LED bulbs (make sure it is the correct side of polarity or else the vehicle will record the error message again). If the LED bulb is installed, but the polarity is incorrect, you will have to start the troubleshoot again from step one (1).
- Close all the doors (trunk and hood if open as well), lock the vehicle and then unlock, and wait 10-15 seconds. After this period, start up the car and turn on the lights to check for the error message. This is a strange procedure to do, but what we have found in the past is that it does work out well for the majority of the vehicles we’ve dealt with.
