Inexpensive signaling fun

I kept the shop lights and rigged up a way to pop the LED lamps in securely. I cut a pair of short dowels and screwed the back covers of the lights to them. Then I wrapped electrical tape around one end so they fit snugly in the shop light sockets.

It took me a while to come up with red and green color filters for the lights but eventually decided on lids from old containers for Spackle and joint compound that beautifully fit the shop lights.

I bought an $8.00 plastic light diffusing panel used for fluorescent ceiling lights and cut two disks out of it.
