Flashing Caution Lights Kit (#1733-3)

This is the Flashing Caution Lights Kit (#1733-3) .This kit will produce a very life-like Road Construction Caution Flashing Lights effect. It will flash a set of 3Yellow LEDS at a quick rate and then it will flash a set of Yellow LEDs at the same quick rate and will keep going back and forth. The circuit is based on two LM555 Timers to create this neat effect. Use this in your model train setups or anywhere else you would like a Police flashing lights effect.
The PCB is double-sided, plated thru-hole, 1.50" long x 2.50" wide made of .062" FR-4 epoxy glass. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side with four mounting holes.
This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc. We supply the parts, you supply the ingenuity. You will get the following:
