I have an 05 f150. The lights work fine but when I try to turn the brights on everything shuts off and if I try to flash them nothing happens. I have no experience with wireing or anything like that and any help is appreciated. Thanks.

 

I am not a expert but if i was you i would check a fuse first if thats not it sounds like you have a short in the line. I work with low voltage, phone systems and when i get a short it kills everything. I am not an expert so take this for what it is. Good luck.
