Here’s a video of the exterior position indicator I removed from the elevator at the building demolition in January.
These indicators are found on many elevators, where the building owner wanted an exterior indicator to show where the elevator is. On 1990′s Dover Impulse elevators, where the building owner wanted exterior lanterns as well, these indicators are mounted on a bigger assembly sandwiched between two directional lanterns, which is very commonly seen.
This is a standard “fake LED” indicator which was used on many Dover installations. Instead of a real LED display with a circuit board, these have number and/or letter bezels which are shaped to look like there’s an LED display behind them, when in reality each position has two incandescent light bulbs behind (#85 bulbs) which light, explaining why the “numbers travel across the indicator”, as many say, versus real LED’s where the one display can be isolated in one spot on the indicator. Both this indicator and the car panel indicator are incandescent.
These days, it’s difficult to find an old Dover with one of these exterior indicators fully working and not at least a little bit burned out. Because the bulbs stay on 24/7, they never get a break and die pretty fast. When they do die, many building owners don’t care about replacing them, resulting in many of them being dead and serving no purpose at all. It’s also a rare to find an Impulse with real LED indicators, but I’ve seen them.
In my case, when I got this indicator home to test it, every single bulb was toast, with exception to one of the replacement LED bulbs which was malfunctioning for some reason. I replaced all the bulbs in it with new #85 incandescent bulbs I bought online.
