08 ford f250 headlights not working

[ygim]

It started with the drivers side then while we were trying to figure it out the passenger went out now I have no headlights except the highbeams.
any help appreciated, thanks

I had a 150 older than yours, but maybe this applies. There is or was some type of fuse or relay in the switch on the dash. One light going out before the other would seem to point elsewhere, but I remember the high beams still working. The fix was to replace the switch. Good luck with it.

Hey ygim have you tried to replace the light bulbs

[ygim]

Yes i did. have to work on it more today. Was out plowing sll night with just highbeams making people a little unhappy.

[ecurbthims]

Are these plow lights or the original truck lights ?

[ygim]

Both so it has to be something with the wiring or the isolation module

i have power to the passenger side bulb changed the isolation module still no driver side headlight
