Hi Kumar, I'm pleased to assist you. Start by turning the engine off and the vehicle is in part. Open the hood and locate the fuse box. Look for the fuse labeled headlight of HL. Remove the fuse, and wait about 10 seconds before reinserting the fuse. Start the engine and turn on the headlights to check if the warning light is reset. The warning light should no longer be illuminated on the dashboard. If the warning light persists or the headlight issue persists after resetting, there may be an underlying problem with the headlight wiring or another component.
