Fog light help
Hey guys got a question here i have auxillary foglights wired to the rocker switch on my brush guard and just installed bulbs in the head light assembly do i need to up the ampage of the fuse if running both because my friend said he had to because his fuse was popping I dont want to burn up the wiring but I figure thats not likely because mercedes doesnt skim on the wiring any help would be appreciated thank you.

They need their own dedicated fuses. That's the way I would do it. If both sets of lights are hooked directly to the factory harness and run simultaneosly you will overload the wiring and fuse--not good.

The fuse on that circuit supplying both auxiliary and the integrated fog lights is 15 AMPS. So 180 Watts total should be okay. Seems you have 220 Watts installed?
