3156/3157 CAN Bus LED Bulb - Dual Function 30 SMD LED Tower - Wedge Base
Overview
CAN Bus LED replacement bulbs can fit vehicle reverse lights, turn signals, and side marker lights. This dual-contact, dual-function 3156/3157 bulb has 30 LEDs that create a 360° viewing angle for better, allover light emission with reduced hot spots. The error-free LED bulb is designed to communicate with your vehicle's CAN Bus computer system and prevent "bulb out" error messages. Tower-style design with a 16-mm wedge base for easy plug-and-play installation. The energy-efficient bulb operates within a 12-24 VDC range and is designed to last 25 times longer on your car, truck, SUV, or van than incandescent bulbs. Available in cool white or amber color. 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. |  |

Well built but not bright enough
As always, very efficient shipping and excellent customer service. Well built and rugged bulb but not quite bright enough to use as a reverse light as it was categorized.
Response from Super Bright LEDs:
Used for front/rear turn signals 2001 Sequoia
4 bulbs in front (parking/blinker combo). 2blinkers only in rear. Rears wouldn’t light up.. since they are dual-function bulbs, they weren’t wired to light up in my vehicle. I just bent the 2 outer wire leads toward the center, and they blink on bright circuit just fine. Fronts lit up for parking/flash(brighter).
I thought can-bus bulbs wouldn’t hyperfash, but they did (I re-read description and found they will hyperflash). Ordered an led compatible flasher relay to fix for just over $10, and no more hyperflash. Easy flasher relay changeout for this vehicle.
Been installed for a week and all is good. While you can find less expensive bulbs out there..beware of failure rate, as less expensive usually = cheaper.(been there).
Over the last few years, I have swapped incandescent to Superbright LED bulbs in my cabin cruiser (all bulbs), and interior lighting on a couple cars with ZERO bulb failures. Superbright LED’s are the way to go!
