    hey yeh the LEDs do flash but they do stop after wen the car is locked! The on board comp does not like them but i ave them in the front as sidelights n do not ave any problems! Got used to the bulb light on the dash!
    I think them flashing at the front look pretty cool!

    You can get led's compatible with the veccy's self checking computer I think. have a look on e-bay. Wonder what the local law would think of flashing front sidelights????
    Now I need a turbo to keep up!

    These are the ones you want mate - as close to led light as you'll ever get, but with no bulb warnings...

    It's the current going through them mate. The buld warnings operate on the principle that the bulbs generate a certain amount of resistance in a circuit at all time, whether on or off. If the resistance bcomes huge, ie the bulb fails, the it puts up the warning, whether the lights are on or off. LED's use so little current that their resistance must be huge from the start, so the computer thinks it's an open circuit.

    Or somethign along those lines...
