vroddrew said:I first became familiar with H.I.D. lighting through my bicycle training. When your training regimen required 40-60 miles per day, and you had a full-time day job, early spring and late fall training rides pretty much meant you needed a good light on your bike to avoid becoming roadkill. And H.I.D. lights have some real advantages for bicyclists: they are MUCH more efficient at turning electric power into usable light than incandescent bulbs, which typically turn 85% of that energy into heat. There is a good early description of the H.I.D. process here .
With that said, I'm not totally sold on the H.I.D. process for motorcycles. For one thing, we aren't as concerned about battery life and efficiency of converting power into light for a very good reason: Our motorcycles have a very handy device called an alternator that generates all the electric power we need for lighting purposes "for free".
Secondly, while we might wish that we could mount searchlights, etc. on the front of our bikes, the fact of the matter is that both the law and other road users would probably (and rightly) object if we did so. The brightness and direction of lights fitted to motor vehicles is pretty tightly regulated by government regulation. I've heard of more than one person getting a traffic ticket for operating his high beams in a situation where he probably should not have done so.
The third main concern I have with the H.I.D. process is the lack of a second (high) beam bulb. If you've ever had a bulb burn out (and trust me - they do) its sort of nice to have a second beam to help you see the road on your way back home. (I'm guessing a police officer would be more sympathetic to me operating my bike with the high beam on if I could show him that my low beam was inoperative.)
I agree that it is a neat (and potentially useful) technology. But until I see more development for use in motorcycle applications, I'm going to steer clear.
The wiring and fuses should have no problem with an 85 watt headlight. I'm running TWO 85 watt headlights on the stock wiring and stock 15 amp fuse. No smoke yet!awtrott said:Does anyone know the maximum wattage allowed for our MC, that will not blow the fuse or worst melt the wire harness and connected components?

You didn't exactly ask about this, but here's another piece of the pie. Can the generator/alternator handle the extra wattage of an 85 watt bulb (compared to the stock 65 watt bulb)? My service manual indicates the generator/regulator can provide 22 amps @ 1200 rpm, and 36 amps @ 3500 rpm. If we assume the low rpm case, and lets say 13 volts, we get (22 amps) x (13 volts) = 286 watts. At the higher 3600 rpm we get 468 watts. Ok, that alone is plenty for an 85 watt bulb, but first we must subtract for the tail/running lights, ECM/TSSM/IM/Spark/FuelPump, and two radiator fans. My quick check suggests the fans may be as high as 85 watts each (ouch). The tail/running lights should be less than 30 watts total (don't stand on the brake, and run the turn signals all day), and the ECM/TSSM/... is under 1 watt (mine measures 0.87 watts when the fuel pump is running). So if this is correct, we have:
85 watts (fan 1)
85 watts (fan 2)
30 watts (tail/running lights)
1 watt (ECM/TSSM/...)
= 201 watts (without headlight)
Now, if we add an 85 watt headlight (assuming high and low beams are not on at the same time), we get 201+85=286 watts. Oops, we are exactly at the 286 watt limit if the engine is idling, and the fans are running (without brake light and turn signal). BUT, we are well under the 468 watts if the engine is at or above the 3600rpm point (riding). Now, I'm probably a bit high on the fans, so in reality, it's probably fine even at idle. And, I'm guessing you would be in quite a unique situation if you leave your bike idling for a LONG time (tens of minutes or hours), and the fans are running the whole time (VERY hot day). So, I would assume (based on these calculations) that the generator/regulator can easily handle an 85 watt headlight.
The "real" HID lights consume far less power (half or better) than standard bulbs, so they would improve the power margin even though they produce more light.
My bike has FOUR fans, and TWO 85 watt headlights. So far I have had no problems. But then again, like Kaz, I don't sit around idling much!
I'm somewhat interested, though I may want a complete pair.

I will be happy to split the cost with you !! PM me.V-Man said:I’ve found a place to get a pair of brand new Hella ballasts (all German car manufacturers use Hella ballasts as OEM equipment) plus Phillips 4100K bulbs for $300 + shipping, does anyone want to split it with me?
On eBay. If you're thinking of replacing both the high and low beam I don't think it's going to work, you really need a reflector to cover the bulb from the front (only low beam has a reflector).Zijspan said:I'm somewhat interested, though I may want a complete pair.
