It should also be noted that turning HID bulbs on and off constantly is hard on them. They last a long time, but this will shorten the life of the bulb. To aid in this, I used a switch to turn my low beam off before start-up. If you're bike is like mine, when the key is on the "on" position, your headlight comes on, then it turns off as you're starting your bike, and then back on when it starts. This is obviously bad for the bulb, so that's where the switch came in. Pretty simple deal. I can take a pic where I mounted it if anybody cares. Some people use a relay to do this process. I read where some people use the alternator to flip the relay. I tried this, but the alternator doesn't put out consistant power, at least not after the regulator which is where I pulled the alternator power from. I called the local dealership, and their electrical guy said NOT to do this. He said that it might be ok, but it could possibly screw with the fuel injection and other things. Point is that it really didn't work like it should theoretically, and it could possibly screw other things up. Just use a switch OR a relay that is thrown from another power source that is ONLY on when the motor is on. I couldn't find one, and the electrical guy didn't know of one either, so I just used a switch. Here's a diagram of how to wire it up if you find a good power source that is only on when the motor is running. Just substitute that for wire that I have labelled "from alternator".
Also, ballasts, when first started, draw more power than your stock halogens, so you will most definitely blow a 10A fuse if you turn on both bulbs at the same time. This does not mean you can't have both on at the same time, but you can't turn them on at the same time. Like I said, they draw more power at first, but then settle down and actually run on less juice than stock. So if you want both on, you'll have to wait around 10 seconds with your low on and then turn your high on.
Well, I can't think if I forgot anything, so if you see any holes in this makeshift tutorial, let me know and I'll fill it it. Also, if anyone with photoshop wants to do me a favor, I'd like you to save all these pics, make sure they are less than 1 meg and just post them directly through this site by attaching them to your reply. I used photobucket, and although I don't plan on deleting them off photobucket, they probably won't be there forever which won't help people that find this thread in a search in the future. Hope this all helps
