    Hi,

    i have build some sort of speed controller for dc motor, and now wanna to make some light effect - some leds in front of car when driving forward, other leds in back of car when driving backwards.

    my idea was connect directly to motor, is this ok?
    motor is deriven by PWM (~100Hz) will it work with leds?

    are any sort of leds wich produces more light?

    Cheap LEDs are dim unless their case pocusses them in a narrow angle.
    Good LEDs are bright and wide angle.

    LEDs have a limited reverse voltage. You'll need to check the specifications for your individual LEDs.

    Each series string of LEDs should have their own limiting resistor.
