The Diode Dynamics 2A LED PWM dimmer with bypass is a positive-channel 12V PWM controller ideal for automotive LED rings, bulbs, and arrays. Rated for 2 amps and 9–16V operation, it uses DIM and HIGH inputs so a low signal produces dimmed output and a high signal passes full power. This makes it perfect for running/turn or running/brake switching with an adjustable dim level.
