If you are wanting to light up the road to see deer at night I think you will find the cowl lights are mounted to low to provide the illumination you are seeking. I bought a set of Clearwater Darla LEDs and mounted them under the mirrors. I chose Clearwater lights because they are the only LEDs that i have found that come with a rheostat that enables you to adjust the brightness. When on the full bright setting they throw light way down the road.

Good luck in your search. By the way I have Kuryakin Led cowl lights which I leave on all the time because they make me more visible to the cagers.
