I run TrippLite LED lights in all of my shell...headlight and auxiliary lights. Very nice stylish and effective lights for the money. On the R3T the lightbar is standard. Any light you put out in front helps but the auxiliary lights really do their best illuminating the perrifery of the road. Definitely helps out on the sides of the roads at night.
I love the illumination of the LED lights over stock. One note...I put my lights on in the winter and never checked the alignment of the headlight. I hadn't done any night riding so one night I decided to take my bike for a ride and check things out. It was a good thing I did because the LED headlight was aimed to only be about 60 feet in front of me. I had to raise my shell up considerably to get it down the road so I could see. When I got things set, it was a big WOW factor. The high beam is really insane as well. As dusk approaches, but still quite light out, if I hit my high beam it lights up the road signs like you put a spotlight on them. Just crazy! Illumination my friend...illumination.
