2. How the Bulbs Work
These switchback LED bulbs operate with dual functionality:
- DRL/Parking Light Mode: When the vehicle lights are on, the bulbs illuminate with a bright 6000K white light, serving as daytime running lights or parking lights.
- Turn Signal Mode: When the turn signal is activated, the white light will turn off, and the bulb will flash amber-off-amber-off continuously, providing a clear and noticeable signal. Once the turn signal is disengaged, the white light will resume.
- Vehicle Lights Off: When vehicle lights are off, the bulb functions as a regular amber turn signal bulb, blinking amber-off-amber-off when activated.

6. Кыйынчылыктарды
If you encounter issues with your Alla Lighting LED Switchback Bulbs, consider the following common solutions:
- Hyper Flash or Fast Flickering: LED bulbs draw significantly less current than traditional incandescent lamps. This can sometimes cause the vehicle's turn signal system to detect a 'bulb out' error, resulting in rapid flashing (hyper flash).
Чечим: Extra LED load resistors (not included with bulbs) may be required to resolve hyper flash. These resistors simulate the electrical load of an incandescent bulb. Consult a professional or your vehicle's manual for proper installation of load resistors. - Лампочка күйбөйт: Ensure the bulb is correctly seated in the socket and the socket is securely locked into the housing. Check the vehicle's fuse box for any blown fuses related to the lighting circuit.
- Incorrect Color or Functionality: Verify that the bulbs are installed in the correct orientation. While these bulbs are designed for compatibility, some vehicle electrical systems can be sensitive. Re-check connections and ensure no wires are pinched or damaged.
