Back in about 1990, our department purchased/installed a small, self-contained strobe with a blue filter (lens) for the unmarked unit. It was about 6" wide, and about 2" tall, squared-off black housing with a 2-volt cigar lighter plug...I vaguely recollect that the back of the unit had some kind of fins (to dissipate heat?) When it was running you could faintly hear the capacitor charging up in the unit until it flashed (kind of annoying, but definitely not as annoying as the previous teardrop incandescent light's spinning motor). It had no external adjustments for flash rate or patterns, or even an on/off switch (as I recall...we just pushed the plug into the cigar lighter socket to activate it). It flashed relatively slow, about 1 flash per second. It was a true strobe light (not an LED). About a year or so later, it was replaced with a Whelen dual strobe head unit that mounted to the top of the windshield that alternated strobe flashes (red/blue), and it had a separate power supply/control unit. Anyhow, I am trying to identify that old school dash blue strobe. I want to say it was a Whelen unit, but I cannot locate any photos of that unit performing Google searches, so I am uncertain if it was Whelen. Our Chief was a staunch Federal Signal guy, and everything prior was always Federal Signal, so I vaguely recollect I was surprised that the blue dash strobe was not a Federal Signal device. But I am trying to recall something from 30+ years ago so my memory is not as sharp as it once was. Anyhow, as I have exhausted my memory and Google searches, I thought it might be worth a try to reach out to this forum and see if my description of this little, slow-flashing dash strobe rings a bell with anyone here to help me identify the make/model of that unit.
