    Have recently modified the Signals on our cars, 'off road use only' but have passed the TUV/MOT with no problem.
    this is them in operation
    I want to know if I can, like the Uk spec VW jetta/passatt have the signals on their brake/tail lights, What sort of driver would be able to accept this, am I looking at SMT LED regulators? or will this have to be transistorised and have resistors put in the circuit? The front was completed with a current limiting chip, accepting from 6-18 volts and outputting 280 ma constantly, along with 3 transistors holding 9 leds at half brightness to be brought up to full brightness upon signalling.
    Can anyone help?
