if i plug in a test lamp to the plug at back of head light the bulb lights reconnect to head lamp bulb nowt surly if power is getting to bulb it should light up thanks for your reply rc pilot

 

I just had this - the passenger headlight went out - then the drivers side about a week later. The brights worked. Replaced bulbs and the bulb sockets

Ended up going to the mechanic - it was the module - about 700-900 from dealer, but they located a used one - 300.

Hope this helps
