I got this at Habitat several years ago. It works but the face of it does not light up as implied. Does anyone know if this uses a replaceable bulb or how to change it? I tried taking it apart a while ago but was not successful, and I didn’t want to break it.
I’d guess it’s from the late 60s or early 70s? | ||

I'll try another go of taking it apart soon | ||

Well I got it apart. Apparently the top button just pops off which I think is what I was missing a few years ago.
Anyway, there is some kind of bulb wrapped in shiny tape, which shines through a plastic disc and illuminates the dial material. I think it must be a neon bulb from what I’m reading on the rolling number type clocks. It appears to be soldered in. One thing I thought was interesting is this appears to use the Telechron type motor, which I believe was a division of GE before they sold the clock and timer company to Timex. I wonder if those stamped numbers “S5 70” are a date code? I did a little research but they don’t seem to fit the pattern for one. | ||

If it is a neon bulb, it will have a resistor in series with it. It's very likely the resistor is burned from decades of use. I would replace it anyway for safety's sake. The neon bulb can be visually inspected. Firstly, a neon bulb has two metal rods inside that do not touch, instead of a filament. Second, if the glass is darkened, the bulb may still work, but not much light will get past the dark spots.
Neon bulbs are still easily had for cheap, and so are resistors. I'd have to look up the resistor value needed, if the old one cannot be read. Unwrap the bulb, let's see what it is. | ||
