Model D2  -    12 VDC, Adjustable, Alternating Flasher

This two channel light flasher is a complete wig-wag/ lamp driver unit which will operate any 2 light, dual signal setup.  It's perfect for Rail Road crossing lights and School Bus No Passing lights or anywhere you need 2 lights that flash alternately.  This unit can even be used in single channel applications where only one channel is needed to flash.

D2 flasher, 2x3 inch, DC Adjustable speed flasher- with two speed ranges

This flasher module is only 2 by 3 inches so it easily fits inside the case of most lights.  It uses reliable, solid state circuitry so there are no relays, thermal switch (blinkers) or other mechanical components to wear out.  Because it uses Highly Efficient solid state Technology the unit is totally silent and will switch up to 50W @12VDC per channel.  That is 4A per channel!   Unlike thermal flashers the Model D2 will not change speed as it heats up and will even continue to flash if one bulb burns out.

Also unlike thermal flashers the speed may adjusted to the exact speed you need with the rotary adjustment knob on the top of the board, from more than 3 times/second to once every 3 seconds. An easy to follow hookup diagram is included with each unit.

Perfect For your Rail Road Crossing Lights, School Zone lights and Flashing Caution lights.
