Please Don't
I would have to agree with Droopy and Roktman,
Noen lights are one of the worst, ugliest, nastiest things around.
When I see that tacky crap on a vehicle of any kind, I just shake my head and wonder why anyone would do such a thing. Rates right up there with the god-awful sounding exhaust the kids are putting on the ricers. Tacky, Tacky Tacky.
But it's your truck, do what you want
