The Stovebolt Site Forums The Shop Area The Electrical Bay Trouble switching from incandescent to LED taillights

bartamos, I know it's sounds fictitious but the turn signal switch that was on the column is a three wire switch. I believe it was a dealer installed item but I can't say for sure. Mine is a 1957 big bolt, 12 volt from the factory. When I bought it there were remains of two running/brake lights and two turn signals on the rear. The turns were totally independent of the run/brake circuit. I replaced all of the cobbled lights and ran new wire to the rear and have two modern medium duty truck tail lights with run/brake/turn in one unit that uses a traditional 1157 bulb. The turn signal switch has one input and two independent outputs. I wired two DPDT relays so I could use the front fender mounted signals as turns and use the rears as run/brake/turn. It works like a dream and I wanted to keep the original switch - and it's a self canceling switch. I mounted clearance/marker lights on the grain box to meet DOT regs and I run those through a separate toggle. I still have to wire my mirrors for lights and heat but have not decided on where to run the wiring yet.
