Hello,

I have a different take on this Dim light problem.

This web site shows how resistance/Ohms changes when you change the wiring configurations.
System Impedance Calculator
http://www.speakerimpedance.co.uk/
2 Series | 2 Parallel | 3 Series | 3 Parallel | 4 Series | 4 Parallel
2 Parallel & 1 Series | 2 Series & 1 Parallel | 2 Series & 2 Parallel
They might be talking about speakers but resistance/Ohms is resistance/Ohms.
Just make believe the speakers are lights.

This web site shows Volts to watts calculator
http://www.rapidtables.com/calc/electric/Volt_to_Watt_Calculator.htm
6 volts DC with 45 amp generator = 270 watts

Does anybody know the resistance/Ohms and wattage of the stock rear 6 volt bulbs?

Can you buy 6 volt bulbs with different Ohms and wattages?

Trying to stretch my gray matter. smile
