What would be the best way to run a set of extra lights. Straight off the battery with a toga switch or a wire off the head lights. Yes there will be a fuse used. I was thinking of running a separate wire witha toga switch.

LOL I had to fix a few more things on my 400 before I will be able to do the lights. I will let you know as soon as I get it done. Thanks for the reminder.

Your alternator is rated at 147 watts at 5000rpm. Figure the total wattage of all the lights (including the ones you intend to add) then allow at least 50 watts for charging the battery. If you exceed the wattage of the alternator, you may have less than full brightness of any of the lights, a battery that dies while you are driving or (worst case) a burned out alternator and/or burned out rectifier/regulator.
If you just have to have blazing hi-intensity lighting, take the alternator out, send it to a rewind shop and have it wound for higher output.

I would recommend a wire directly to the battery and a toggle switch - us a 16 gauge wire (or heavier) and fuse the wire as close to the battery as possible. Also run a separate ground wire of the same gauge from the light to the battery negative terminal.

The alternator is rated at 147 watts - layman's terms, a little over 10 amps - at 5000 rpm

The stock lights and battery consume 3.25 amps - the battery consumes .9 amps to charge. The battery can draw a maximum of 4 amps if low or in poor condition. If all the lights are on and battery drawing 4 amps, the total demand on the alternator would be appx. 7.25 amps

As long as the battery is in good condition, you could add 2, 30 watt lights and probably be safe (total draw of all lights and the battery on the alternator appx. 8 amps) - exceed that and you will most likely need to charge your battery after riding. Also, you could expect the alternator, the rectifier/regulator or both to have shortened lives due to the higher output demanded from them.

Happy motoring :)
