I went with a 5 3/4 Bullett headlamp, Put in a PIAA bulb and added a set of HD's Halogen "Engine Guard" ( $150.00) mounted Fog Lamps. You cant imagine the amount light these baby's throw. I can finally spot, at quite a distance, animal & deer eyes reflecting from both sides of the roadway. The HD Foglamps are small, but their shape puts out a bright and wide beam... and since they're mounted a bit lower and wider... it really lights up the road ahead.
Love them

 

Remember the RK has the aux lites. I put a set on my lowrider and wouldn't be without them. At night, in critter territory I keep it on lo beam just so I won't lose the aux lites. They make it look a little old school to boot
