Chris,

The stock alternator will eventually suck your battery dry of charge running a standard 55W/60 H4. You can do a couple of things -

Snag an HID conversion for @ $40-$50 off of Ebay like this:

OR you can send your alternator out to be rewound:

Last time I asked he was getting about $180 to rewind a T500 alternator to give enough juice to run a 55W/60 bulb and keep the battery charged.

OR you can step up to a powerdynamo generator:

These are very well made and I know a few folks that use and like them. With shipping to the USA, you're looking at about $500.

So there's three options. Fang (who used to post a lot on this board when he had a T350) did the HID conversion on an RD350 and said it gave plenty of light. I would avoid switching the taillight to an LED bulb. In my opinion the taillight on a T500 is small enough (even the double bubble on a '75) without reducing the output further with an LED.

Just as a reference point, Kevin rewound a Hitachi low speed coil for one of our TZ250s (sold) and he did a great job. Nice fat blue spark at lower revs than stock.

My T350J model runs a 55/60 H4 bulb without any trouble while using standard bulbs everywhere else.

The wiring is standard without the green to red/green swap for extra output and there are no problems charging the battery while riding.

Considering the meagre alternator output from the T350 I would have expected the 500 to also cope with a 55/60 H4.
