This is an old Western Electric trouble alarm lamp with two brass rings, a red glass cone lens and one green glass cone lens. I picked up from our local reuse place so I am guessing it was from a small switchboard or C.O.?

I disassembled it and cleaned the plastic/glass using mild dish soap, and hit the brass with a wire brush wheel. The lamp originally uses these wooden wedge base B2 switchboard incandescent bulbs but I am switching it to LEDs to save the bulbs and make it low voltage friendly. I used some left overs from an addressable LED strip (Adafruit.com) and mounted them to small strips of plywood with 3M doublestick mounting tape. I marked out the holes in the paperboard corner that I saved as it great to do mockups with and It fit better than I expected. I also had some of these leftover addressable NeoKey LED switch mounts (Adafruit.com) and filled them with leftover Cherry MX blue clone switches (novelkeys.com).

I might just drop it down to one switch as two makes it seem too bulky. I also picked up at reuse a small lot of tiny box hardware and cleaned up some brass screws from it to attach the switch sockets.

I am hoping to use this as a simple event timer that after an hour it goes from Green to Red alerting me that I need to take a break from the project I am working on at the bench.

Stay Tuned and please take care of each other.
