Car: 2012 Acura MDX
Problem: Passenger low beam headlight is out.

I replaced it with a new bulb, it is till out. I replaced it with a bulb I know for a fact functions, it is still out.

What do I do next? How do I figure out where the problem is so I can fix it?

Please help if you can,
-Beck

 

Bulbs arent the only piece of the puzzle, could be the igniter, ballast, relay, etc. you’ve ruled out the bulb, now move on to the next
