If it was me I'd unplug the rear light switch connector and see if the light goes out. Then cross the terminals with a bit of wire and see if the light comes on. If it does then you know your wiring is ok and the switch is the problem. If the switch is the problem try taking the rubber boot off the top of the switch and spray lots of wd40 into it and then work the spring up and down with your hand. Then adjust the height of the switch again.
