Fog Lights issue

Just got a new to me 2007 Tundra. It has what looks like aftermarket headlights and fogs or maybe just smoked appearance? Anyways the headlights are very bright and work well but fogs will not turn on. All other lights work and I changed fog fuse with no effect. Anyone familiar with these? Could the headlights be affecting fogs as ecu doesn’t think they are on? They are bright but not sure if led or hid? Hopefully picture attached shows the headlights.

thanks

I would start by checking voltage at fog lamps input wires and go from there, meaning you have to trace back to where the power ends to find the problem. Luck.

 

Forgive me if you if you already know this, but, your fog lights only come on if you have your headlights on low beams and not high beams with the fog light switch on.

 

Good advice..
With that stated, one can wiring diagrams here..

This is assuming no modifications were done to the OEM wiring.

Thanks for the wiring info, yes I know the headlights must be on. Do the headlights look led or hid? How do tell? I have always just stuck with stock ones.
