I'd like to make the lighting more reliable and am interested in using LEDs. My primary design change would be to have a ground wire to the lights rather than relying on the base itself for ground.
I was thinking that an LED light with pigtails for brake/clearance/ground would be ideal if it would fit in the existing base. Or is there a way to convert the 1156/1157 base to a more modern connection?
About 95% of all unreliability of lights could be traced to a bad ground, as I'm sure you know. Corrosion from the socket, then to the can, the can to the base, the base to the body, and then the ground on the other end. Rebuilding the sockets or replacing the cans, then cleaning up those connections would be the best way.
I have seen where a ground wire was run straight to the frame to improve the circuit. It was fished down threw and inside the wall.
In some cases LED lights could be straight wired but one would have to be careful when it comes to LED lights. Some of them have drivers and resistors in the sockets to lower the power to allow the LEDs to handle the power.
