I just got done putting a set of 100w aircraft landing lights on my truck for driving lights.
I've never had really bright lights before, and these made my brights look like I was just holding a flashlight out the window. For less than $70 (including wiring that can handle several more lights) I've nearly tripled my light output.
Still in the shop
My camera doesn't like to take night shots, so they're not the greatest.
High beams and driving
I need to get some pics of the difference from inside the truck now. I also have pics of the install that I'll probably put up later.
