4. Installation Guide
The SEALIGHT X1 HB3/9005 LED bulbs are designed for a quick and easy plug-and-play installation, typically taking around 10 minutes. No additional tools or modifications are usually required for most vehicles.
4.1 Before You Begin
- Ensure your vehicle is turned off and the engine is cool.

- Confirm the bulb type is HB3/9005.
4.2 Installation Steps
- Disconnect Power: Carefully disconnect the electrical connector from the back of the existing bulb.
- Remove Old Bulb: Twist or unclip the old HB3/9005 halogen bulb from its housing. Remove it gently.
- Insert New LED Bulb: Take the SEALIGHT X1 HB3/9005 LED bulb. Align the tabs on the LED bulb with the slots in the vehicle's housing. Insert the LED bulb and twist or secure it until it is firmly seated. Ensure the LED chips are facing horizontally (3 and 9 o'clock positions) for optimal beam pattern.
- Connect Electrical Connector: Reconnect the vehicle's electrical connector to the new SEALIGHT X1 LED bulb. The bulbs are non-polarity sensitive, meaning they will work regardless of connector orientation.
- Test Functionality: Turn on your vehicle's lights to test the new LED bulbs. Ensure both bulbs illuminate correctly and there are no error messages on your dashboard.
