I have an old 12 volt strobe from RS Components, the electrical supplies
company and the ref. no. is 565-440. It happens to be orange, but I would
think the glass is interchangeable.

I used this 12V strobe from RS. Took the flash tube out and mounted it inside
the clear anchor light so that it did not obstruct the light bulb already in
there.
The electronics from the strobe were re housed in a PVC tube with end caps and
the lot was fitted just under the anchor light inside the mast. 3 wires led
down from this, common , anchor light , strobe. Since there would never be both
lights on a single common wire was sufficient and a 3 core mains cable could be
used to run inside the mast.
