This simple kit uses a handful of discrete components to flash a single LED at a low level using an extremely low average current. The kit runs from 3-12V DC and will run continuously from a standard 9V PP3 (transistor radio) battery for years, the current consumption is so low.

Ideal for adding marker lights to equipment or for marking out paths, or anywhere else you need a low power marker light that you will never need to turn off.

We supply the kit with both a 5mm narrow angle white LED and a 4.8mm wide angle superbright white LED, but you can use any small LED.

Short form kit including PCB and all components. Note that the PCB solder pads are quite small, so 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 below.
