i couldn't find this in previous topics...
we've got a random fault recently starting: when indicating (more often with near side indicating than off side indicating) the indicator stops working and the sidelights/main lights bulbs light up on the dashboard, which itself goes slightly dim (as it would when the lights are turned on).
it even does it when you're not indicating now, but it seems to stop when i touch the indicator stalk. i can't replicate this at home but i noticed, today, that the lights were visible on the rear of the car in front.
i've also noticed the dashboard is forgetting it's last brightness setting; it doesn't go really dim, but it isn't as bright as I last set it; i'm wondering if this is connected somehow.
i found somebody had cut the rear wires to one of the rear light clusters - and badly soldered them together; i've repaired those properly, but it hasn't helped fix the fault. i've also replaced many of the bulbs (front indicator bulbs, brake bulbs, rear indicator bulbs), but this hasn't helped either.
i'll be checking the front sidelight bulbs/headlight bulbs in the morning, but i do know that all the bulbs are working as we frequently check them (ex-trucker and some habits die hard!)
a friend said it was probably an earth fault, but i don't know where else to start looking and thought i'd ask here before paying for an auto-electrician...
can anybody suggest anything I can do next or where might be a likely candidate?
cheers in advance
