This simple kit uses one IC to alternately flash two pair of LEDs, much like the flashing lights on emergency vehicles. The kit runs from 9V to 12V DC and will run from a 9V battery, 12V battery or a regulated power supply.

Ideal for providing a very attention-grabbing flasher - both flash rate and alternation rate are adjustable.

We supply the kit with 4.8mm wide angle superbright red and blue LEDs, but you can use any small LEDs.

Short form kit including PCB and all components. While the kit uses all through-hole components, you will need a fine tipped, temperature controlled soldering iron to make this kit.

Note, we no longer include printed instructions with our newer kits, please download the instructions at the Documentation link below.
