Frequently Bought Together


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.

Important Notes - Please read before purchasing:
  1. Your vehicle may require an LED compatible Flasher or Load Resistor. LED brake/tail lamps will not flash with most stock flasher units due to their extremely low current draw. Try our Vehicle LED Bulb Finder to find a compatible flasher for your vehicle. Please See More LED Car Bulb Notes
  2. The supervision resistor built into CAN bus bulbs are not intended to fix turn signal related issues, such as hyperflashing. Please See More CAN Bus Bulb Notes
  3. CAN Bus bulbs should work with most cars that have computers that notify you if a light bulb is burned out. However, some vehicles still might have issues - due to the unique electrical systems in these types of vehicles. Please See More CAN Bus Bulb Notes
  4. Oversize
  5. For best results the LED color should be the same as the lens color. If bulb is behind a clear lens, use the appropriate color for turn and brake light functions. Please See More LED Car Bulb Notes
  6. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.

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:

When using in a single use type of socket with this bulb, it may be necessary to reverse the bulb in the socket to access the brighter output.

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!
