I'm a big fan of the VisionX Motorsports lights. I am not seeing any metion of them here on ExPo but they are definitely well known in the Baja curcuit. They do have a line of incandescent lights but are better known for their HID and LED lighting. They are definitely the front runners in using LED for offroad lighting applications. In a lot of ways LED makes a lot of sense.
1) Vibration resistance
2) Lower amp draw
3) Long Life
4) Less heat
Check them out. I am putting a set of the adjustable beam HID 6503 on my new ARB bumper in a week or so. They are in-cab adjustable from pencil spot to flood beam at the touch of a button.
When I get a roof rack speced and built for an RTT I plan to add a 42" LED bar across the front for additional lighting. After seeing the review pics on their site between regular high-beams vs. two HID 6500 series vs. Xmitter 42" LED bar I was sold:
