The Secret To Using Flashing LEDs With DCC (302)

Flashing LEDs can be very useful on a model railroad to add a little animation to water towers, buildings, and radio transmitters among others. And if you have a DC power bus on the layout, powering them can be quite easy. However with DCC power there is a secret to making them flash. In this video I'll show you how to power them using good old DC power and then I'll share my secret for powering them using DCC power from the track power bus or from an accessory power bus. Below are the part numbers as I promised. Be aware that you can use a smaller bridge rectifier such as the 1/2 amp one I have also listed. You also probably can use a smaller capacitor if you only need to light a couple of LEDs. In this case I was able to do 5 with a single capacitor.
