    You do not need to PWM for a tail light
    First u need to find the forward voltage drops of the LED's that you have.
    For this u need a 5V supply or a li-on battery and a multimeter

    just search the forum for "tail brake light led" you will find plenty of circuits and ideas to build your own.

    More to the point, brake lights are critical safety components. The reccomendation is to use a guaranteed LED lamp replacement, or not to do it at all. Functioning brake/turn signals are too important to try as a hobby attempt.
