May be a dum question. But MAD (madelectrical.com) Said that with older cars its better to install a dual relay on the headlights to make them brighter then normal. Because of the drop in volts. Like nearly 14%. I believe relays will help. But with that said,why stop there. If it makes the headlights brighter with the drop in volts. Why not install realys on the tail/brake lights to have brighter brake lights on older cars and maybe even on the wire going to the distributor. Wont they have a better out put with relays installed. Or am I thinking wrong ? Anyone done this ? Seems like the 14% volt drop should be throughout the car,if it is to the headlights. The guys that install aftermarket power windows in old hot rods will have more powerful power windows I guess to with relays also.
