Frequently Bought Together


LED replacement bulbs are designed to fit vehicle front turn signal lights with clear lenses while also functioning as daytime running lights. This 3157 dual-contact, dual-function Switchback bulb has 30 amber and 30 cool white enhanced LEDs (2835 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots. Tower-style design with a 16-mm wedge base for easy plug-and-play installation. The energy-efficient bulb has 12V DC operation and is designed to last 30,000 hours on your car, truck, SUV, or van—25 times longer than incandescent bulbs. Not sold in pairs. Price per bulb.

This type A bulb shows white color when parking lights are on and signals amber when turn signals are in use. Alternatively, a type B bulb shows white color when parking lights are on and alternates between amber and white when turn signals are in use.

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. Oversize
  3. 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
  4. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.

Installed on a 2005 F150

I installed these switchbacks on my 2005 F-150. All I can say is WOW! These babies are super bright, in both the white and amber! I opted to use en electronic flasher relay instead of going with load resisters because I intend to do my taillights, etc. The light from these bulbs thoroughly fills up the reflector, causing it to be very bright and full, even in full daylight. I have 6000K HID lights, and these flashers compliment them very nicely. Other companies I found were selling switchbacks for 100+ dollars, and I can't imagine how they could be any better than these. At first I was slightly skeptical because of the small size, but my skepticism quickly disappeared when I installed and tested them out! I definitely will be turning to SBL for my rear turn signals!

2014 F150 Ecoboost

Make sure you purchase the recommended load resistor or you will have hyperflash. These switchbacks really blew me away. My favorite thing about them is they blink amber-off-amber-off. I was not expecting that for $30 and it was a great surprise. second photo is halogen amber vs the white LED's.

Installed in a '13 F-150 Platinum

Very pleased with the results!! My truck has clear lenses, and the parking light mode is nice & bright - turning your previously amber parking lamps into Daytime Running Lights. It is a very white light, just a tiny tinge of blue. The amber mode is a nice deep yellow/orange - very close to the original incandescent.
(On my application the load resistors were necessary - older vehicles may get away with an electronic flasher/timer unit)

Wish the bulb could work correctly above 12 Volts

I installed these switchbacks on my 2015 F250 with 6 Ohm/50WATT load resistors. They are excellent brightness (white and amber) with the engine off. However, with the engine running and charging at 13.8V the amber mode “strobes” with directional or hazards activated, and are of dim inconsistent brightness.
Tech Support sent 2 replacements which behave nearly the same. When I reported to tech support the recent results ( with videos)they said they were going to run tests but have not heard anything from my email submission to support
I am concluding since these lamps are spec’d at operating voltage of 12 Volts only, they don’t operate correctly above 12 volts (i.e. engine running with charging ~13.8V). All the other 3157s have a voltage range such as 9V-14.8V. The other LED bulbs I have in the vehicle work and switch fine (engine on or off). I would suggest to a buyer of these bulbs to visually check the operation of directional/hazard mode with engine off and on to ensure they perform

Response from Super Bright LEDs:

Vehicle electrical systems must be relatively stable for LEDs to operate steadily. Any grounding issues or voltage regulation issues may cause LEDs bulbs to react oddly.

Get the Tail Light Load Resistor Kit too!

Save yourself time and frustration and order a Tail Light Load Resistor Kit when you order these bulbs (one kit for each bulb), and get some extra 20 gauge wire and connectors because the wires pre-installed on the Resistor Kit are not long enough for you to be able to mount them where they need to be after they're connected to your bulb socket's wires.
