1157 Switchback CanBus White / Amber LED Turn Signal Bulbs – Pair
Upgrade your factory 1157 bulbs with RMS Lighting White / Amber Switchback CanBus LED Bulbs. These dual-function bulbs illuminate white during normal parking light or daytime running light operation, then automatically switch to flashing amber when the turn signal is activated.

How the Switchback Function Works
Normal Driving / Parking Lights: WHITE
Turn Signal Activated: FLASHING AMBER
When the turn signal is activated, the white light turns off and the bulb flashes amber-off-amber-off for a clean, highly visible turn signal.
Once the turn signal is canceled, the bulb automatically returns to white.
Important Application Information
These bulbs are designed ONLY for dual-function applications where the same 1157 bulb operates both the parking/running light and turn signal.
They will not provide the intended switchback function in a single-function light socket.
⚠️ LED Flasher Relay May Be Required
LED FLASHER RELAYS MAY BE REQUIRED FOR SOME VEHICLES.
Although these bulbs are CanBus compatible, some vehicles may still experience hyper-flashing after converting from incandescent bulbs to LEDs.
Please Verify Fitment
Please check your vehicle's owner's manual or original bulb number to confirm that your application uses an 1157 dual-function bulb before ordering.
Vehicle applications and electrical systems can vary, so please verify compatibility before installation.
