led bulbs on positive ground
I've been using 1157 LED bulbs for years and they outlast regular filament bulbs 100 to 1. You must rewire for instance the rear brake switch to ground for the LED to work. Current only flows one way pos to neg in an LED. I get the red LED 1157's in cheap 2 packs at the chain auto part stores. It saves carrying an extra bulb in your pocket.
