i had a wikid problem with my lights in general, when i indicated, a random exterior light would flash and random lights on the dash would come on, like fog light!

Corsa GSI electrics are amazing, the shit they can do sometimes, i had a headlight problem, you would turn the igniton off take the keys out and the car was still running you could drive it no problem. only switched off when ya turn the headlights off + if ya turned the headlights on with no keys in the ignition lights came on and you could bump start it.
I wont even start on the hazard light problem thats most corsas have

r u sure u havnt just hit the dimmer by the lights, im always doin that, its not off, its just very dim. im gonna take mine out soon, pisses me off

the mfd in my corsa gsi lights up when ignition is turned on but goes off when lights are turned on. is it meant to? if not, is it a common problem and how do u fix it?
