Installation Guide
The FAHREN H1 LED bulbs feature a 1:1 mini design for direct replacement of your original halogen bulbs without the need for additional adapters or modifications. The installation process is typically quick and straightforward.
Preparation:
- Ensure your vehicle is turned off and the parking brake is engaged.
- Disconnect the negative terminal of your vehicle's battery to prevent electrical shorts.
- Locate your vehicle's fog light housing. Access may vary by vehicle model (e.g., from under the hood, behind the wheel well liner).
- Wear the provided cotton gloves to avoid touching the LED chips.
Step-by-Step Installation:
- Remove Old Bulb: Carefully disconnect the wiring harness from the existing halogen fog light bulb. Then, unclip or twist to remove the old bulb from its housing.
- Insert LED Bulb: Insert the FAHREN H1 LED bulb into the fog light housing. Due to its 1:1 mini design and non-polarity feature, it should fit directly into the socket. Ensure it is fully seated and aligned correctly.
- Secure the Bulb: Reinstall any factory latches or clips to secure the LED bulb firmly in place.
- Connect the Plug: Connect the vehicle's original wiring harness to the FAHREN LED bulb's connector. The non-polarity design means it can be plugged in either way.
- Test: Reconnect your vehicle's battery. Turn on your fog lights to test the new LED bulbs. If they do not light up, refer to the Troubleshooting section.
