LED Headlight Bulb Installation Guide

After installation, the LED chips should face the 9 o’clock and 3 o’clock positions, with the power cable connection interface positioned at the bottom.
Tools You’ll Need
Before starting the installation, gather the following essential tools:
Gloves – Protect your hands from heat and potential injuries.

Start by disconnecting the car, then open the hood and locate the existing headlight bulb, usually located behind the headlight assembly.
Next, gently rotate the old bulb counterclockwise to remove it from its socket. Avoid using too much force to prevent damage. If the bulb is stuck, you can use a one-piece screwdriver to loosen it slightly to release the clamping mechanism.
Then, insert the new LED headlight bulb into the socket and turn it clockwise until the bulb is secure. Avoid touching the LED chip directly as this may damage the bulb.
Once the bulb is installed, connect the power supply.
Before closing the hood, turn on the headlights and test the high and low beams. Make sure the light is evenly distributed with no glare or dark areas. If necessary, adjust the bulb angle so that one LED chip faces the 9 o’clock position and the other faces the 3 o’clock position, with the power cord pointing downward for optimal illumination. Installation is complete when the light is bright, clear and properly aligned.
By following the above steps, you should be able to successfully install the Lezen 110W LED bulb. We encourage every user to remain patient during the process and strictly adhere to safety guidelines.
