the light is just an indicator letting you know they have been turned on, and it extinguishes LONG before the glow plugs do.
watch the cabin light when you turn on the key, it dims when you power the plugs, and it does not brighten until the plugs shut off... often around 45 seconds after you turn the key.

I hope you've posted that for others to know how the glow system works; I've been a w123 owner for 14 years. The plugs are all working units but the relay is not operating as designed. My plugs stay on for less than 6 seconds- I've a helper turn the key- while at the relay you can both hear and feel the relay switching on and then off within 6 seconds. I currently do not have a spare relay but will look in the yards here soon. W123 are not showing up like they used to anymore...
So please as I asked- post more info about my previous request. thanks.
