Anyone that has not done this modification, I think should because it is a BIG difference and in one night I know it saved me from hitting at least three deer. I got the lenses off of E-bay and they came with bulbs in them and I purchased the wiring harness from suvlights.com. Only thing I had to do was cut out some of the inside fender to make the lights fit, and the day time running lights no longer work as a result of the wiring harness I would guess. However so far so good with no hot wires or added stress to the system that I can tell.
