Want to copy the headlight from a custom

The headlightlight on the magna got smashed up when the girlfriend dropped it (it's her learner, then project bike) and I don't want to replace it with another dinky poor quality square headlight.

I saw this custom chopper that had two small oval headlights mounted one on top of the other with a 4 inch clearance. I found two identical (but not chrome) driving lights at walmart and I know I can make it work but I have two questions.

1.) Do you think two driving lights will give me a good amount of light?

2.) How would you wire this up? One light on for normal driving and two for high beams? Or would you have them both on and mount two 55w fog lights to come on for the high beams?

The idea is to give the bike a totally different look by the end of the summer.

I'd stick to 2 lights. Your alternator will not keep up with 4 lights. It may struggle with 2 55 watt lights. It will definitely not keep up with 4.

I have 2 extra 50 watt lights. Unless I keep my RPM up over 4 K RPM, it doesn't keep up. I have a voltmeter guage (I added) and watch the volts go away if the bike isn't at high RPM.

If I am stop and go traffic, I turn the lights off. Don't want a dead battery.

Really? She seems to keep up well with ~100 watts of electric warming gear and the 2 55watt fod lights I had on this winter and that was in the D.C. bumper to bumper commute...

You'd have to know what your generator output is... and also list everything that you run. you were running with `200 watts of aftermarket junk on there already - most 80's alternators only handle 300(ish) watts total - I think you might be pushing your luck (And you battery) to the limits.

Then again, the magna might have either a larger output alternator, or your bike might have an aftermarket.

Whatever you do, I would suggest going with a complete rewire for the headlight - you'll get brighter light and be guarding against meltdown of the stock wiring if you overload it.

This guy does great work if you don't feel like wiring it yourself - http://www.easternbeaver.com/Home/Main/main.html

So would the driving lights work as a headlight alternative? I don't want to dish out teh money for two $100 lights just to find out that I don't like the look on my bike.

we put a set of just cheap auto zone lights in the one on two bright formation. it was seriously bright (even in the single mode) but for some reason everything looked kind of "shadowy" he said it didn't bother him and still uses it that way
