NAOEVO LED Headlight Bulb Installation Guide

Correct Beam Angle

Proper installation is key to getting the best performance from your LED headlight bulbs. Make sure the LED chips (diodes) are positioned side to side—one set pointing at 3 o’clock, the other at 9 o’clock. This alignment provides even 360° light distribution, resulting in a uniform beam and a well-lit headlight housing.

Step 1: Gather Tools
Before you start, prepare tools such as a socket wrench, screwdriver, and (if needed) a trim removal tool.

Step 2: Access the Headlight Assembly
Open your vehicle’s hood and find the back of the headlight assembly. Depending on your car, you might need to remove a cover or panel using a screwdriver or trim tool.

Step 3: Remove the Old Bulb
Disconnect the wiring harness from the old bulb. Depending on the socket, either twist it counterclockwise or release the retaining clip, then take out the old bulb.

Step 4: Install the New LED Bulb
Align the LED bulb’s tabs with the socket slots. Avoid touching the LED chips directly—use gloves or a tissue if needed. Insert and secure the bulb by twisting it clockwise.

Step 5: Reconnect the Wiring
Attach the wiring harness to the new bulb, making sure the connection is firm to avoid flickering.

Step 6: Test the Headlights
Before closing everything up, turn on your headlights to check that the new bulbs work correctly.

Step 7: Reassemble Everything
Replace the cover or panel, ensuring all clips and screws are secure.
