Q, I have them mounted to my engine guard on my 2012 Custom with lowers and they really light up the road.
I tried them with the Daymaker Headlights disconnected and they were so bright I was sure if I loose my headlights I'd still be safe with the Daymaker reflective Foglamps working.
Get a hold of PCPaiN if you decide to get them.
Hope this helps.
