    I'm going out on a limb here, only cause I'm from an electrical background, but I suspect the LED lighting does not draw enough current to make the car think the (conventional) light bulb is working. It thinks the bulb is blown.

    so if i replace it with a LED with the same current usage, that should solve it?

    No, you will need to build resistors into it to make sure the blown globe light isn't illuminated on your dash. The system sends a small electrical current that is complete if all globes are operational. If a tail light globe blows for example that signal is broken and the warning light comes on.

    Check Mav's site here for better info.

    it has the warning light comes on around 6watts and because LED is less than that, hence it thinks it's broken.
    then can't you just put in high Watt LED bulbs?

    Did you read the link I posted? You have to put a resistor either around the LED or in the wiring.

    yeah i did read it.
    but i dont understand how many resistors i need.
    it saids 1 resister per bulb and the bulb was like 1.5w?
    so how does that exceed 6watt, which is what the warning light is about.

    Mate - no offense, but if you don't understand basic electronics and the information in the link that Ozram posted, then maybe you shouldn't be mucking around with the electronics on your car! You don't want to cause an issue which creates a problem which won't be covered under warranty....
