Safety Information
- Always disconnect the vehicle's battery before attempting any electrical work to prevent electrical shock.
- Wear appropriate personal protective equipment, such as gloves and eye protection, during installation.
- Ensure the vehicle's engine is off and cooled down before handling light bulbs, as they can be hot.
- Do not touch the LED chips directly, as oils from your skin can reduce their lifespan.
- Verify that the bulb type (H4/9003/HB2) matches your vehicle's requirements before installation.
- Dispose of old bulbs responsibly according to local regulations.
Setup and Installation
The LUXSTER HolyKnight LED bulbs are designed for straightforward installation. Follow these steps for optimal performance:
- Preparation: Ensure your vehicle is turned off and the engine has cooled. Open the hood and locate the headlight assembly.
- Access Old Bulb: Depending on your vehicle model, you may need to remove covers or other components to access the existing halogen bulb.
- Remove Old Bulb: Disconnect the electrical connector from the old bulb. Unclip or twist to remove the old bulb from its housing.
- Install LED Bulb: Insert the LUXSTER HolyKnight LED bulb into the headlight housing. Ensure it is seated correctly and secured with the retaining clip or twist mechanism.
- Connect Electrical: Connect the electrical connector of the LED bulb to your vehicle's wiring harness. Ensure the polarity is correct; if the bulb does not light up, disconnect and re-connect with reversed polarity.
- Test Functionality: Turn on your vehicle's lights to verify that both LED bulbs are functioning correctly. Check for proper beam pattern and brightness.
- Adjust Beam (if necessary): Some vehicles may require minor beam adjustment after LED bulb installation to ensure optimal light distribution and prevent glare for oncoming traffic. Refer to your vehicle's service manual for adjustment procedures.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | Incorrect polarity of electrical connection. | Disconnect the electrical connector, reverse its orientation, and reconnect. Test again. |
| Dashboard error message or flickering. | Vehicle's CANBUS system detecting incorrect wattage or bulb type. | LUXSTER HolyKnight bulbs are designed to match 55W halogen power to prevent most CANBUS issues. If issues persist, a separate CANBUS decoder may be required for some sensitive vehicle models. Ensure the vehicle and lights are fully off before turning them back on after installation. |
| Light output seems dim or uneven. | Bulb not seated correctly in housing; headlight lens is dirty. | Re-seat the bulb firmly in the housing. Clean the vehicle's headlight lenses. Ensure the LED emitters are oriented correctly (e.g., 3 and 9 o'clock positions if adjustable). |
| Excessive glare for oncoming traffic. | Headlight beam aim is too high. | Adjust the vertical aim of your vehicle's headlights. Consult your vehicle's manual or a professional for proper adjustment. |
