I wonder if anyone can help me with some brake light wiring questions. I finally decided to add an extra pair of brake lights to my stock 41 Plymouth P-12 coupe. It originally only had the single, trunk mounted light, which just doesn' cut it in modern traffic...too many times people don't notice me braking. I added two NOS 6 volt "Guide Lamp" style lights with red lenses on the rear bumper, and connected the wiring to the existing single brake light wire. I installed 6 volt, 20 watt halogen bulbs. It worked fine initially, but eventually blew the single 30 amp fuse in the main lighting circuit. Following some on-line tech tips, I tried re-routing the hot wire from the brake light switch directly to the solonoid on the starter, and installed a 20 amp in-line fuse. This bypasses the main light circuit and keeps the central fuse from blowing, but when I tested the brake lights for several minutes I noticed that the ammeter now jumps way to the positive side and the brake light housings get so hot they literally start to smoke! Is this an issue with the halogen bulbs themselves, or is re routing the hot wire to the solonoid a bad idea? Should I just ditch the halogen bulbs and go back to regular (dim) bulbs, and/or switch the wiring back? Maybe I'm the dim bulb here.....
