Just so ya'll don't think I'm too nutty...here's what I was thinking -
Busa puts out 400 watts, stock
Subtract high (60w) and low (55w) beams for a remainder of 285 watts. (everything else is LED, negligible watts)
H-D (FLH series) standard output is 480 watts, police bikes are at 540 watts, and the 07s are now at 585 watts. BUT they have almost no LEDs so their remainder is not that much more than ours, maybe a 100 watts or so.
The upgrade in the post that I saw (from Rick's Motorsport Electrics) talked in terms of a 25% upgrade - about 100 watts!
That puts me back in all the heated winter gear I could ask for! Especially if it can be done for, say, $250 or so.
Thanks again for all the help!
