Setup and Installation
The NOVSIGHT A500-N35 LED bulbs are designed for a plug-and-play installation, closely matching the size of standard halogen bulbs (HB4 9006). No additional harnesses are typically required.
- Preparation: Park your vehicle on a level surface, turn off the engine, and engage the parking brake. Disconnect the negative terminal of your vehicle's battery.
- Access the Bulb: Locate the headlight or fog lamp assembly. Depending on your vehicle model, you may need to remove certain components (e.g., air intake, battery, or fender liner) to gain access to the back of the bulb housing.
- Remove Old Bulb: Disconnect the electrical connector from the existing halogen bulb. Then, unclip or twist to remove the old bulb from its housing.
- Install LED Bulb: Insert the NOVSIGHT A500-N35 LED bulb into the housing, ensuring it is seated correctly and securely. The 1:1 halogen size design ensures compatibility with most vehicle housings.
- Connect Electrical: Connect the electrical connector from your vehicle's wiring harness to the NOVSIGHT LED bulb. Ensure a secure connection.
- Test Functionality: Reconnect the vehicle's battery. Turn on your headlights/fog lights to verify that the new LED bulbs are functioning correctly. Check both low beam and high beam (if applicable) and ensure the beam pattern is correct.
- Final Assembly: Reinstall any components removed during step 2.
Important Note: If you encounter any issues with fitment or functionality, or if you are new to automotive lighting installation, please contact NOVSIGHT customer service for assistance. They can provide installation videos and support.
