The louder the better
I will be surprised if you don't want the 4 Hi mod after a while. As it is when the highs go on the lows go off and it does drop the overall light coverage even though you can see more distant objects. It also looks kinda strange as most quad headlight setups are "all on " when the brights are on . Thanks for the additional info on the backing plate. I expect I will be doing mine when I get a few hours to attach together but I am installing the headlight mod, the horns and the temp sensor all as one project.
What year model is your truck? The only reaso i had to drill is because mine is an earlier model, if yours is a 1994+ then you wont need to
