Ok, On the subject of bulbs, I have seen several aftermarket 100W+ bulbs for sale in sites like Dennis Kirk, JP Cycle, ect, and I have found that you do NOT need to go with one of them for extra light.
Sylvania Silverstar Ultra H4 bulb. It says 50% brighter and 50% better distance. I think that's wrong. It appears, at least to me, to be closer to twice as bright. And they draw no more juice than the stock bulb. Only costs $25 for a single bulb. HUGELY expensive compared to most any other H4 bulb, but still WAY less expensive than HID (or, even crazier in price, LED headlights)
The only caveat I can say about them is supposedly, their lifespan is shorter than stock, though I had one in my Shadow for over three years, and never once did I have a problem.
