We had Unity spotlights on most of our mountain trucks at the phone company. They basically looked just like yours, unchanged. They only lasted a couple of years and then the switches would get so rusted up they wouldn't work, or they wouldn't swivel easily. We'd just replace the whole unit, (unlimited phone company money). We always kept a couple of them in stock in the parts room. When we brought those vehicles down off the mountain for a service, they had to go back up that same night. You're losing two-hours driving time. No time to mess with a spotlight that had issues, just throw a new one on. They always needed brakes all the way around and everything else the drivers destroyed; the mountains tore those trucks up and they kept them for over 15-years, mileage didn't matter. The drivers up in the mountains had to have the spotlights in the fog to spot the addresses on the houses or even to find the road they were driving on it. Sometimes when drove up there I had to do it with the door open just trying to follow the line in the fog, it gets nasty and dangerous up there, you couldn't t see the end of the hood on some nights. I don't miss that part of my job one bit. The Untidy spotlights worked well, when they worked.
