Land based radio shops are under "two-way radio" in the yellow pages,
or you can ask your local fire dept., police, public works dept.,
etc... for the name of the shop who installs their radios and strobe
lights. The rubber plugs are usually less than a buck.

They come in limited sizes (3/8", 3/4", 7/8" and 1-5/16") because those
are the only size holes we punch in cars for 2-way antennas. They are usually
plastic. In general, they stay in well, seal well, and last for a year or two.

Your local installer of truck and construction equipment accessories
who sells strobes and warning lights may also have them.
