Our iJDMTOY 27-SMD 3157 Bi-Color LED Switchback Bulbs are the new and updated version of our previous 54-SMD Bi-Color LED Switchback Bulbs; these bulbs feature a brand new SMD LED diode that produces both the Xenon White and Amber LED colors in one. The new technology allows these bulbs to be the about twice as bright as any similar style bulbs on the market.
Switchback LED bulbs are lit as Xenon White during the Parking/City Light Mode and blink Amber when the turn signals or emergency flasher lights are engaged.
These High Power 3157 Switchback LED bulbs will fit a variety of sizes that include 3057, 3457, 4057, 4157, etc. These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb.
This Known Compatible Vehicle List includes all of the currently known vehicles that use this product, but there
may be more vehicles not on the list that can also use this product as well.
We recommend installing load resistors with these bulbs to prevent hyper-flashing or error messages.
