Hey guys, I work in the heavy construction industry and recently had strobes and some auxiliary lights installed on my '12 Fx4, all was fine for a week until my passenger headlight went out. No biggie I thought, swapped the bulb out and still nada, replaced the fuses inside and still nothing. The only electrical experience I have is finding out why one should not stick metal things into wall plugs, so any help would be greatly appreciated!

 

Let's start with the easy stuff. You said you replaced the fuses. Were they blown? Could they be blown again? Have you tested for both power and ground at the connector?

 

Hi & welcome!

I'll take a different tack - pay a visit to the feller who did yer strobe work to Diagnose and FIX what is almost certainly an issue he caused as a result of an inattentive/sloppy install.

Be calm but firm and insistent - only go Postal if he turns out to be a jerk

This is especially recommended if you have zero automotive electrical experience as you have noted. Do you even own test equipment?

I for one do not believe in coincidence.

Good luck!
