I've got an issue with my 2003 Impreza RS. Never had it happen in any other car before so not sure if it's a Suby thing or not.
A couple of days ago I noticed my passenger side tail light was on, car not running and locked. I tried all the light switches etc, car running and not, nothing, it wouldn't turn of. So I just pulled the bulb, fixed



I have looked at the wiring at the back of the tail lights and saw red, white and blue electrical tape about 60mm from the bulb socket, is this factory/normal? It is neat though. Also there are three wires that come out of the tail park light bulb socket and the white wire with black trace (on both sides of car) are cut and taped. Is this normal?
Any advice to fix/diagnose will be much appreciated. Also I'm a Chippy so if it is electrical diagnostic advice please explain as if I'm dumb

Cheers
