Auxbeam 1156 LED Bulbs for Backup Reverse Lights, Super Bright 6500K White P21W BA15S Bulbs for Car, 3030 33-SMD Chipsets Bulb with Projector, Pack of 2 (May Need Resistors)

Having used other Auxbeam LED's previously with excellent results, I ordered these. They offer a magnifier over the working end & four LED strips at 90* from each other around the circumference. The fixture housing them has a chrome plated interior. These lamps, mounted horizontially, fire the magnified end directly to the rear while three of the circumferential strips illuminate the reflective interior. The fourth projects to the side. Combined with the increased brightness of LEDs, they provide a turn indicator with greater visibility to surrounding traffic. I expect them to last a long time, like other Auxbeam LED's I've used.

I bought these to upgrade the headlights on my garden tractor. They work great. I can now mow all night and annoy the neighbors. Very bright. Easy replacement.

​I swapped my old halogen brake lights for these Auxbeam LEDs, and the difference in visibility is night and day. The Good: ​Projector Lens: Unlike cheap LEDs that just have chips on the sides, these have a glass projector lens on the tip. It shoots a focused beam straight back, making your brake lights significantly brighter to the driver behind you. ​Distinct Brightness: A common issue with LED 1157s is that the "running light" and "brake light" look the same brightness. These have a clear, sharp contrast—dim for running, blindingly bright for braking. ​Color: Deep, rich red. (Always use red LEDs behind red lenses; white LEDs make the lens look pink/washed out). ​Build: Solid aluminum body, feels heavy and dissipates heat well. ​Important Note: ​Size: These are longer than a standard halogen bulb because of the projector lens. If your tail light housing is very shallow (like on some older motorcycles or flat trailer lights), measure first to make sure the lens won't hit the plastic cover. ​Hyperflash: If you use these for turn signals, you might still get "hyperflash" (fast blinking) on some vehicles despite the "Canbus Ready" claim. You may need to add a load resistor. For brake lights, they are usually plug-and-play. ​ One of the best safety upgrades you can do for under $30. They are instant-on, super bright, and look modern. Just check your housing clearance first.

I like the night visibility of these lights and the quality of these bulbs very much. Functionality is quite fine. Installation is a breeze and so is fitment for my use. The only problem I had was thinking that using clear bulbs in the red and amber lenses would make them easier to see or visible for longer distances. It made them worse actually, please buy the appropriate colors for your lenses if this is your desire. The colors will pop and day-time visibility will be so much better. Which was my goal 100%. The look is very great and the durability has to be great too as it has a very nice weight to them and it just says quality. But time will tell of course. As my use was for turn signals I just automatically used resistors with them as the first turn signal bulb I replaced with LED hyperflashed I just added resistors with blinker bulbs after that, I didn't know for sure that this bulb set required it or not.

they are bright! definitely an improvement over incandescent bulbs.

Problem: These "plug-and-play" LED turn signal bulbs do not function correctly in older vehicles, specifically my 1979 Ford F-150. While the blinker flashes, the running light completely shuts off during the signal, which is a major safety and functional issue. Details: Installation was simple and seemed correct, with the bulbs fitting into the original sockets. The running lights worked normally until the turn signal was activated. When a turn signal was used, the running light on that side would completely turn off instead of alternating between running light and blinker. This is dangerous and makes the turn signals much less visible, especially at night. This is likely an electrical incompatibility issue with older vehicle systems that the product fails to address, despite being advertised as a simple installation. Conclusion: The bulbs are falsely advertised as a simple plug-and-play solution for a 1157 bulb replacement. For vintage truck owners, these are not a direct replacement and will require additional modifications, such as wiring in load resistors (which often get dangerously hot), to function properly. This is an unacceptable product for anyone expecting a straightforward install and safe operation.

If anyone has tried LED signal bulbs in most newer cars, you will quicky find out that the CANBUS system that controls everything does not work correctly with LEDs. This is because they don't draw enough amps. The system goes into hyper flash mode to warn you that you have a burned-out light. So, the manufactures of LEDs came up with the idea of having built in resistors to trick the system into working correctly with LEDs. They call them CANBUS ready LEDs. Problem with that is the resistor defeats the purpose of installing LEDs in the first place and cause the bulbs to get really hot and put just as much strain on the system as a regular incandescent bulb. This causes the bulb to not last anywhere near the expected lifespan of an LED. That being said, I installed these non-resistor bulbs in my 2016 Ford Explore after having terrible luck with the resistor type not lasting very long. As expected, the system went into hyper flashing mode so in the dash the flasher and lights flash about twice as fast as normal. But in this car on the outside the lights are flashing at the normal speed they should. So, I will live with it. They are nice a bright and come on instantly as they should. Hopefully they will last a long time since they don't have the hot resistors in them.

Super bright ease of installing

muy buenos

Exelente iluminación los recomiendo

If these are used as brake light bulbs, there is very little brightness difference between the low intensity illumination from being on for visibility at night, compared to the higher intensity when you press the brake pedal. This makes it dangerous as drivers behind you will find it harder to realize you are braking. I had to remove these bulbs and put back the regular dual filament incandescent bulbs which have a much greater brightness difference between brakes applied vs brakes not applied.

Stopped working after 6 months

Did not work on a Ram 1500, had a lamp out light show up and it hyper flashed, best to buy a resistor
