Hey guys new here and new power stroke owner (2007 F350 Lariat CCSB). This may have been covered already, but I have a an issue with this truck and the lights. I’ll list what I did and what it’s doing.
BEFORE CHANGE:
Headlights= stock bulbs
Fog lights= stock bulbs
AFTER CHANGE (UPGRADE)
Headlights= LED
Fog lights= LED
here is the issue. After I installed the headlights and fog lights I went to test them and found the fog lights would not turn on (I made 100% sure they were plugged in correctly). I also noticed that when I tried to turn them on, the high beams would activate instead of the fog lights. I can also see the high beam indicator lit up on the dash when I turn on the fog lights. So I did a little diagnostics and found the following.
NOTE: THESE ARE A PLUG AND PLAY SET OF LIGHTS FOR BOTH HEAD LIGUTS AND FOG LIGHTS. THEY CAN ONLY BE PLUGGED IN ONE WAY
DIAGNOSTICS:
the above diagnostics tell me when I have the LED headlights installed, this is causing the issue. So my question is, can I do something to keep both sets of lights working 100% correctly when they are both using LED’s? Thanks for any help guys.

DIAGNOSTICS:
- checked all connections, fuses and had the key turned on
- removed LED fog lights and installed factory bulbs and kept LED head lights (still didn’t work and had high beams still turned on with fog switch)
- removed LED head lights installed factory bulbs (everything worked 100% correctly like factory)
- installed LED head lights again (keeping factory fog light bulbs) and it went back to turning high beams on with fog light switch.
- I removed the LED head lights and put stock bulbs back in (again back to functioning 100% correctly)
- I removed factory fog light bulbs and installed LED’s (with new LED fog lights, the truck continued to function 100% correctly like factory)
