Hi Guys, not sure if this is the place to post an issue about headlights but I'd figure I would give it a shot.
During last weeks storm my driver's side headlight on my 08 Fisher 8'6" plow with intensifire lights went out. I replaced the bulb with the plow still attached to the truck and it still wouldn't come on. I then detached the plow from the truck and noticed that the driver's side headlight was out on the truck. I then replaced the truck side bulb and that won't come on either.
Does anyone have any ideas before I start digging into the engine compartment for fuses, wiring, etc? The truck is a 2008 F250 CC diesel. The directional bulbs on both the plow and truck are working as well as the truck fog lights and the passenger side on both truck and plow are fine. The high beams on both plow and truck for driver's side are also not working. Any help is greatly appreciated!

Drivers side Low Beam Headlight

This happened to me last week as well ? I took it in to the Plow repair place & they changed my H13 light connector, It was still not working & they disconnected the plow lighting Module & told me to take it in to the Dealer!!
I knew there was a problem with the wiring on the truck side as I checked it out myself before. I found a brake in the left Low Beam light wiring. But the fuse is ok for each front (there separate for each) I now have apointment for a shop I trust to check out & try and find the wiring problem on Monday?
I'll let you know what happens & good luck to you to.

Thanks for the response. My driver's side headlight came back on two days ago when the weather warmed up to the low 50's and now that we are back below freezing it went out again. The fuses I checked are good. I guess now I'll try and check to see if the ground is good. I also had someone tell me that the smart junction box may need to be reset. It will automatically shut down power to the headlights if it senses irregular currents. No idea if this is my problem but its weird that it also effects my Fisher plow.

wiring

I wonder if your wiring has a slight brake in it as well? and then makes contact again, Maybe these trucks dont have a good wiring harness. Esp. on plow trucks, There's a wiring problem with mine 100% Good luck

Lights

I just wanted to post up that my issue with my 1 Low beam out, was the electronic component thats after the fuse panel on the pass. side compartment. Its a Microprocessor or something like that that my Mechanic actually bypassed as it would of needed reprograming from the dealer if we purchased it & installed it? Also for the Plow guys out there my Issolation Module needed replacing as well. Last month I hit a Light Post in 1 of the plazas that I do & totaled my fisher plow?
