Wired my lambo lights in the other week, taken straight off how I wired up on my last car before I stripped it. It was a manual, now on the auto when I press the brake pedal the cockpit dispays dim and I can hear a relay click from the auto gear selector. :confused1: Anbody any ideas, as I can't seem to sus it out? Its ok when the lights are already on but this happens when the lights are off, I cant keep driving round with the lights on all the time lol

cheers

sounds like a bad earth feeding back through your reverse lights perhaps

Do you have nornal bulbs in the lights or leds?

Placing a diode inline with the light feeds will prevent any voltage returning back down the line. Also check the little black control box in the panel drivers side, they can play up and cause shorts if water gets into the board.

I got normal bulbs,with the little black box unplugged i get no brake lights at all, I will try my other one though but they where all fine before I converted. I'll recheck the reversing ligh earth, also not really up on me diodes :D have you a link please gover :)

cheers

Lol will find a link for the diodes, they act as a one way gate, let voltage through, but not return. Before you think about the diode route, i would change or check the little black box that controls the rear lighting. If your existing lighting worked fine before you converted, i would check each light wire for a short, most likely got a ground touching live or not grounding properly.

Cheers guys I'll have another look and double check with multimeter, I thought it maybe something particular to autos as it was fine in the manual car. Cheers :)

Im still stuck, the light on the left pod go dull when the brake pedal is pressed, and still the relay click from the autobox selector. Tried a few addition earths also I left myself a red herring last time but I now realised I should'nt have looped the reverse earth, but never made a differance. Ran out of light :( (still drivable though :) lol )

Sorted now, a bad earth on the brake wiring (opps, ffs) cheers :)
