How do you figure the wattage used by high and low beam bulbs? My Banshee has 35 watt headlights but does that mean the each filament uses 35 watts?
For example I have 2 headlights with high and low beams. Is that 35+35 for low beams and 70+70 for high beams? Or is it something like 10+10 for low beams and 25+25 for the high beams for a total of 35+35?
The reason is I don't really need the low beams and I would rather get some Xenon bulbs and modify them to my housing and maybe put a brighter or extra light in the back for better visiblity.
And does anyone know the output of the factory stator on a Banshee?

Yooo! Holyman, I think you would rather know the Amperage over Wattage. I've ponder on this also and I know you can hook up a amp meter inline, ( I do believe), turn the accessories on, and this will give you the total amperage your putting out. I don't know what the stator is rated at though. I could also be wrong on this whole shabang thing, but I'm sure someone on this forum can explain it better than I. I'll be back here to see if i made any sense at all.:-)

Hey, In answer to your question. If you have 2 headlights that are rated for 35 watts and they have high and low beam you would have 35x2 for high beam and 35x2 for low beam. which would mean you need 70 watts to power your lights no matter which beam is in use. as far as zoomzoom's reply you are close. But not exactly. Amperage and watts are 2 ways to measure the same thing which is current. The same 70 watts I spoke of would be 5.185 amps if your electrical system is running 13.5 volts. Hence watts divided by volts is amps. Amps times volts is is watts. Another example: Is you have a 60 watt light bulb in your house. Your voltage is 120 volts. So 60 divided by 120 equals .5 Your bulb is 1/2 amp. or 60 watt Two ways to measure the same thing. Hope that helps.

groundhawg...what you're saying is that each filament is 35 watts so 2 lights on low beam use 70 watts combined and those same lights on high beam use 140 watts combined. Or a total of 4 filaments at 35 watts each. Correct?

Yes if they are 35 watt lights then each filament uses 35 watts each. So if all 4 filaments burned at the same time that would be 140 watts. But all factory setups i have seen only the 2 low or the 2 high burned together. All 4 never burn at the same time. You could strap them to do that but I'm sure bulb life would decrease due to higher temps. inside the bulb. If you want more light go with a higher watt bulb if your charging system can handle it. Your owners manual should say in the specs. section how much output it has.

I finally actually looked at the bulb closely and it says... 12v30w30w. So each filament in the bulb draws 30 watts. If all four filaments don't go on at the same time when the high beam switch is used then the light wouldn't be brighter unless there is some sort of regulator to the "low" beam. Just so I'm clear on this there are 2 headlights with 1 bulb in each headlight and each bulb has 2 filaments. Now I want to know the highest wattage I can run on the stock stator.
