Police Emergency Flasher DIY Soldering Kit

Police Emergency Flasher Light Red and Blue DIY Kit (for toy use only).

The assembled module requires 9-12V power supply (standard 2.1/5.5mm DC plug). We recommend our USB power supply cables.

Make sure you assemble the red and blue LEDs on the correct part of the PCB. A print on the bottom side tells you where the red and where the blue LEDs go.

You can either add 4 wire bridges to the [+] and [-] connections between the control PCB and the LEDs, or you can score and break the LED “wings” off the control board and place them further away using wire connections.

The speed of the light effect can be adjusted on the multi-turn potentiometer R2.

NOTE: You might find a second electrolytic capacitor (10µF) for C1 in some kits, which causes a 10x slower flashing effect than the always included 1µF capacitor.
