  Is there a non-halogen light bulb,6 Volt that is brighter than the stock bulbs available? I do not want to convert to 12 volts or change my good reflectors.

  You might try Ron Francis Wire Works. www.ronfrancis.com.

  It would be good to check with Ron Francis but unless he has changed (please let us know if he has) he only carries 12 volt bulbs. My '32 has been converted to 12 volts and I am using his bulbs. They work "great".

  The original #1000 bulb is 32/32CP. I believe there is a 50/32CP available but do not have the number. The increase in Candle Power from 32 to 50 is not a big increase in brillance of the bulb, but worth a try.

  Mac's sells the 50/32Cp bulb as P/N B13007D.

Headlight output can be improved by making sure that 6 volts is getting to the lights when they are turned on and with cleaning the lens and reflector and properly aiming the headlights.

The way I check for correct voltage at the bulb, is with the lights on, connect a voltmeter common lead to the NEG battery post and the + lead is used to probe the connection as close to the bulb as possible. The meter reading is the amount of voltage drop in the connections.If the meter reads .2 or more, you will need to find the bad connection by moving the + lead of the meter to each connection closer to the battery.

The bullet connectors and the light switch itself are the usual points of voltage drop. At 6Volts your headlights deliver full brightness, this drops off dramatically at 5.5 volts to about 75% of full brightness.
