4 High Mod or Fogs on High

[87stocker]

Is the 4 high or Fogs on high mod doable with this generation of truck? The headlights are mediocre at best on these rigs. Thanks in advance.

I'm curious on this too

The 4-hi mod is for keeping the low beams on with the high beams. That's how the GMT900 trucks come stock, there is no 4-hi mod needed. (edit: at least that's how my truck was when I bought it)

As for the 6-hi mod, I'm actually pretty impressed with the output of the lights as they are compared to my NBS Yukon and Suburban so I never felt the need to pursue it. I did recently replace both of my low beam bulbs because one crapped out, and I was surprised to find a white powdery buildup on both of the bulbs that was really reducing output. Maybe check your bulbs for the same thing and replace them. I'm just running simple Sylvania H11s, not silverstars or any of the overpriced crap, and the increased output with the new bulbs was pretty noticeable.

i wish there was a way to do this too you can over run the lights really fast, my f250 was much brighter, i picked a 04 gmc sierra and did the 6 hi mod and its bad ass
