Still waiting for parts I ordered so I ordered some flashing LED's from Evans Designs, they came on Saturday and I installed them today, they work like a charm, Time to get it working, about 15 minutes. Man do they ever "pop"...

From Evans Designs website: "With a super compact full wave Bridge Rectifier for "always on" forward and reverse operation, a capacitor, and a dropping resistor . . ." They work because they already have the rectifier and capacitor as GRJ mentioned. They will run on 5-19V AC or DC.

Your first purchase of prewired 12V flashing LEDs only have a dropping resistor. They will only operate on filtered DC.

Here is the circuit GRJ was suggesting:

Make sure the polarity of the capacitor matches the rectifier outputs.
