    I have some 3w "star" LEDs, rated at 700ma. I will be using these in an upcoming automotive project.

    I am undecided, and prompt for your suggestion:

    Should I drive them with a RESISTOR or LM317 setup in CURRENT REGULATOR mode?

    Thanks,
    Andrew

    Its for an interior dome light replacement, nothing to do with any exterior lighting, or modification of vehicle's electronics systems.

    How could that be so bad? TOS violation or not, please advise.
