This LED reversing light bulb features a top-mounted cooling fan for superior heat dissipation, ensuring a clearer view when reversing your vehicle, and an extended LED bulb lifespan.
102 high power 4014 SMD chips are arranged in 360°around the bulb in an orderly manner, the SMD components are selected to be more resistant to vibration and impact, which is a better choice for off-road vehicle reversing light upgrade. And the lens on the top makes the light more focused and penetrating.
The LED bulbs of the 2US6T series are designed to be more compact in size than their halogen counterparts, making them easy to install in assemblies where space is at a premium. The compact, double-sided LED chips emit a more uniform beam of light similar to halogen bulbs.
AUXITO's hottest option - The 54H series with the compact lens on the top can achieve a good spotlight effect, and reduce light scattering, while the 360° illumination design greatly enhances the visibility of Reverses.
The CSP series of bulbs are the brightest of the reversing light options, so if you have a T15 reversing light bulb model and are looking for maximum brightness, then the CSP range will fit the bill perfectly. However, it should be noted that they have a large fan at the rear, so you need to make sure you have enough space to install them before purchasing.
Yes. LED reverse lights are one of the most popular upgrades for the rear of an aftermarket vehicle as they simultaneously improve the rear lighting output and increase the appearance of the vehicle.
Reverse lights are also called backup lights. They are used to warn other vehicles and people around the car that the vehicle is about to move backward. The reverse lights also provide some illumination when the car is backing up.
White. It is generally white to differentiate it from red tail lights. It illuminates whenever a vehicle is about to move backward.
Whether an LED light requires a resistor depends on your car model and LED light. If your LED reflector light flashes or jitters rapidly, you may need a resistor. Load resistors can help prevent this issue. If you purchase a light bulb with a built-in decoder, no additional decoder is required.
(If you need to purchase additional decoders to prevent your new LED reversing lights from flickering, check out: Canbus Decoders/Resistor)
1. Check the light bulb: If the reversing light does not work, it may be that the light bulb is burned out. In this case, a new reversing light bulb needs to be replaced.
2. Check the fuse related to the reversing light: a broken fuse will also cause the bulb to not work properly.
3. Check whether the switch is properly connected: a loose or damaged switch may cause the bulb to go out.
4. Check the reversing light sensor: Vehicles equipped with reversing light sensors may malfunction, affecting the operation of the reversing lights. It needs to be repaired and replaced in time.
5. Check the wiring connecting the reversing lights: The connectors and wires connected to the backup lights may be damaged and aged and must be repaired in time to avoid affecting daily travel.
Suppose the above methods cannot solve your back-up light bulb operation problem. In that case, it is recommended to consult a professional car repairman to conduct a fault inspection to find out the specific cause of the problem and repair it.
Tryed another brand after the first Auxito quit. Used them for two weeks and went back to Auxito. I do notice they have an ever so slight interference when I’m listening to AM radio. Yeah, I said AM :).
This jumper has a lot of power, great tool to keep in your car.
When the sun goes down the light stays there with these bulbs. Before when we ran halogen bulbs we were hardly able to see the lines in the road. The led has a great field of view with a distinct cutoff line and haven’t been getting high beamed like most people claim when making the switch. Before and after pics comparing the halogen to led on the wall with in the day time.
Easy to install and super bright, clear light! Just what I was looking for!
Great clear brightness and does not dazzle oncoming vehicles, very happy with this product and quality
Phenomenal! Crazy how amazing these work! Im in love
I’m sorry but I live in Anchorage Alaska and I don’t have a garage so I can’t install the film. Tonight it’s supposed to get to minus five degrees and I’m just not going to be outside working in these temperatures. So I suggest you checking back with me in around April. I appreciate the fast shipping service. Kudos for that.
The Auxito smoked third brake light is absolutely a game changer. Looks great on the truck and alot brighter.
Great chip set like the swichback on it, only thing was it wasn't bright enough for my use when off road every day city and hwy driving great.
Installed this weekend on my ‘02 Ford F-150 Lariat. No hyper flashing, very bright, and they look amazing.
LED bulbs really give my car a little more pop. I’ve replace all the bulbs in my car with Auxito bulbs.
Easy to install. Good quality no warning lights on dash so good so far. I’ve added a photo to show a comparison between halogen and led as you can see there’s major difference between my LED low beams and halogen fog lights
Love the brightness of these lights! Plug and play, perfect!
Got the updated 2025 version of the 9003 bulbs, literally lights up the night. I drive for a living overnight on some dark roads and highways, these lights are game changers. I don’t think I’ve used the high beams once since I installed them, before I could barely see with halogen high beams. Great bulbs!!
Works perfectly fine with the switchback

These lights work well and quietly. However they are super bright and probably not legal despite the led chip placement that is the same as the halogen filaments. I realigned the aim of the lights to reduce glare for oncoming traffic and the poor souls in front of me. I think the light intensity should be less for street legality even though it's s great for me as a driver.
This led lights have a good output for off road
Much brighter than the original lights on my 2018 Silverado. Fit exactly like the originals. Try 'em!
Mines work but keep doing the animation and wont stay on white while driving it just keeps on doing the animation the whole time . And if it does stay on all white it will only stay for like 2 min and start doing the animations again.
Working perfectly. No errors
