Hi there ive just fitted my 1999 4.6 vouge with a HID head light upgrade. The only problem is when you turn the lights on it reads blown bulb left hand side . the new lights plug into the back of the wiring loom on the right hand side were the bulb should go but not on the other side. Is there anything i can fit or do to stop this message comming up?

Dont turn your lights on.

The HID system uses less current when on through the BeCM so the BeCM thinks a bulb has gone....

The HID system when installed should have come with a box of tricks to fool the BeCM into thinking nothing is wrong...

Speak to the fitter/manufacturer for a solution.
