    when I got the car the brake light bulb warning light was on but all the brake lights worked ok.When I started looking into I found that the high level brake light has been wired to the n/s brake light,if I remove the o/s bulb the warning light goes out when I've disconnected the high level light its not working and I've got no power to it I've removed the rear 1/4 trim and checked the wiring from the multi plug to the light with a power probe that's ok so no broken wires in the tailgate.So need to find out if its a broken wire some were and why j have no power to it Just wanting to put the light out if its goin to be a mare of a job, as its poss an mot failure

    Centre brake lights isnt a mot failure as not all cars have them

    So are you not getting power to the rear brake light? Have you traced them wires back to any connections. What do you get there?

    Have you checked the earth of the rear brake. Could be an earth rather then a live

    Does a hyanes manual not show the rear light wiring diagrams?
