Auxbeam 3157 LED Bulbs White, Super Bright 3156 3057 4157 3457 4057 4114 Replacement Bulbs for Backup Reverse Lights DRL Parking Lights, Pack of 2 (Need Resistors for Tail Brake Turn Signal Lights)

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.

Great for the money. Just installed will see how long they hold up. A lot brighter than oem bulbs. Installed on 2018 f150 LED on left Oem on right

These are very bright and good quality

​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.

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.

they are bright! definitely an improvement over incandescent bulbs.

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.
