i was driving yesterday heard a ding ding then i notice the lamp out light on . but i have no lights out on the truck .so what could cause this. thanks

 

Discussed a few times on here. Most times it's the passenger side rear brake lamp (upper in my experience). The lamp may not look bad, but inspect the contacts closely. Replace with glass base lamp - not plastic.

When you remove the housing from the truck, put a towell for paint protection in the hole........ask me how I know.
