Overview
LED replacement bulbs can fit vehicle tail lights, brake lights, reverse lights, turn signals or side marker lights. This 3156 single-contact bulb has 27 LEDs that create a 360° viewing angle for better, allover light emission with reduced hot spots. Amber lights feature high-intensity LEDs that are ideal for high brightness LED applications. Tower-style design with a 16-mm wedge base for easy plug-and-play installation. The energy-efficient bulb operates within a wide 10-30V DC range and is designed to last 30,000 hours on your car, truck, SUV, or van—25 times longer than incandescent bulbs. Available in cool white, amber and red. Not sold in pairs. Price per bulb.

Lumen meters are a great way to measure white light output but can be deceptive for colored bulb intensity. Lumens measure light wavelengths in all colors of the visible spectrum. Because multiple wavelengths create white light and colored bulbs are a single-wavelength source, colored bulbs will have lower lumen readings. However, they will appear equally as bright as a white bulb. | ![]() |

3156 LED Reverse/Backup Lamp
I replaced the original reverse light bulbs (old style incandescent) with the 3156 LED replacements on my 1997 Firebird Formula. The original didn't provide much illumination while backing up, like there was nothing lit back there at all. After switching to these LED 3156 lamps it has made a nice improvement. These are bright white whereas the originals were a yellowish color and nowhere near as bright. I highly recommend them.
You'll see everything behind you.
I purchased a pair of these for my 2000 Ford Explorer, and they're really bright! I'm not sure why the other person says these bulbs are worse than incandescents. They easily produce four times more light than the incandescent bulbs I had before, maybe even more. They're a nice white color which is an upgrade when compared to the yellow oem bulbs, they also completely illuminate the area behind your vehicle, unlike incandescent bulbs which seem to only alert other drivers that you're backing up. Definitely a good product.
