OK so i have a 2005 f-150 and i put some aftermarkets headlight bulbs ,it burned my harness and i got it replaced with some upgrade high volt harness so i put in my new bulbs and same thing happens one side only the driver side keeps on going off but the bulb is good its not burn is just that i wont turn on so if i switch bulbs from driver to passenger side they will work but then and hour later the driver side bulb will go off again i even put the original bulbs not aftermarket and this problems still continues if anyone had this happened to them please help or anyone know what the problem might be i will appreciate it.

 

If your still having this problem it could be ground or fuse related...

 

did they work fine before??

 

Really, again? Did you check the harness? You did something wrong man. Just because it's been almost a month does not mean there is a magic fix. WTF?
