Easy Grade Crossing Flasher Circuits For Your Model Railroad

Ever wonder how to flash your grade crossing signals! In this video I have two easy ways to build your own flashing circuit for your grade crossings. One way is with a 555 timer chip and the other way is with a transistor circuit. Both methods are easy to build and very inexpensive to make.
I made three different circuits in this video but decided the second 555 timer circuit was a little easier to control with different resistors to modify the flash rate. All the components needed are listed in the wiring diagrams at the end of the video and can be obtained from my Amazon link below.
