Don't HID's get their power directly from their own wire (direct to batt)? the other wires just carry the signal to turn them on/high/low beams? even then, the power wire I have on my 55w HID, that I have yet to mount, doesn't seem to be that "BIG" of a wire so it shouldn't carry that much current. if the 35w HID's use less juice than the factory bulbs.. then the 55watt bulbs should use abt the same? again since they get their own juice (from battery) then it wouldn't matter abt current draw. I read somewhere that the 55's don't put out that much light than the 35 watts... and that was on a HID website that doesn't sell the 55 watts because of ..."issues" with the 55 watts? and the HEAT??? it is a ARC, like welding so there is going to be HEAT issue for the lens/reflector?
If you put a relay in, so the headlight wire just triggers the relay, and then the relay closes the circuit between the battery and the HID ballasts, then the draw on the stock headlight wiring will be minimal (it's only triggering the relay). If, however, you don't put a relay in and use the stock headlight wiring to power the HID ballasts, you're likely to have problems.
HID's use less power than halogens when they're 'on', but when they first fire up, there's a pretty significant current draw in order to 'ignite' the plasma in the bulb - why a lot of people put delays on, so the headlights don't turn on until 5-10 seconds after the bike starts - some use the oil pressure switch to trigger this (another relay), so once the oil light goes out, it closes the circuit and the HID will ignite, rather than trying to ignite when you turn the ignition ON, then again after you release the starter button. That initial ignition (turning on) I understand is the hardest on the HID ballasts.
I've read recommendations against the 55W bulbs - my understanding is that they put out MORE heat than many headlight housings are designed for (and the 35W HID's put out less.)
