The Motolights come standard with a 35W Halogen, and optional 50W Halogen. $385 + $15 for the optional 50W bulb.
The engine guard mounted fog lights from Harley are 55W Halogens. Includes switch, relay, and wiring. $139.95 ($127 to the front door from Zanotti's). I've not ridden with the Motolights, but I have ridden with the Harley lights. They are very bright -- as much as I would ever want -- and throw a nice, wide, flat beam. .02
I like the way they look too.

Plus, I didn't want the external wiring with the Motolights. On the HD lights, all internal wiring. Very clean install.
