This article intents to provide guideline on how to diagnose and fix LED strip not working issue for the following headlight models:
International ProStar Headlight Lamp LED (Performance) - Driver & Passenger Side
If none of LED on the strip is not working please locate the LED plug - small grep plug at the very end of each headlight as shown in the attached picture and do the following steps:
1. Twist the small grey plug gently to take it out but not completely since there are two wires connected
2. Switch the wires
This should fix most of the LED strip not working issue.
