Adding a roof top strobe to a Williams U33-C diesel

I have added a roof top "strobe" to my Williams U33-C engine. I used the Miniatronics HO scale roof top beacon. The kit includes an Amber Lens Cap that press fits into a 11/64 inch hole in the roof. The kit includes a 3mm LED and circuit board. I powered the board from track voltage through a diode to limit the voltage applied to the board. The "HO scale" strobe closely matches the size of the strobes that are factory installed on my other MTH engines.

See photo of the Miniatronics strobe kit.
