Saw a lot of different setups at the meet last night, but didn't think about this till now.
I've got a pair of Rigid Dually Floods hiding in the front bumper and old yellow'd headlights on my 99. The LEDs really fill in the short distance and wide view. I love them for seeing around dark corners, finding campsite turnoffs and some camp setup time. But, they aren't really useful above 20-30ish MPH.
I've got an AllPro Apex plate front bumper with no tube-work, so pretty wide open. There are 2 holes already for a pair of normal lights, or I could pretty easily do a LED bar in the 12-20" range. I had also thought about the Ruffstuff 4" HIDs, but looks like they are updating.
What do recommend for more range without going crazy? For a normal style 4x4 doing 40-60 on standard forest roads, not balls to the wall per-running.
