Quoted from z28dan:Spencer's sells a rotating beacon light that plugs in the wall.
comes with red and blue lens.
I'm sure it could be adapted to fit.
price is like $12 or $15.
That was actually my first thought. It is 12VDC so you could toss the A/C adapter and just direct wire it (assuming the original was 12VCD).
Edit: Yet, original motor is 12VDC.. I'll upload a pic of the unit, I have one in a box in my cabinet. DSC00809.JPG DSC00812.JPG
