Climate regulation illumination

[carBlacken]

The climate control in my 1998 R129 functions; nevertheless, despite substituting the bulb in the holder beneath the unit, the light remains nonfunctional, leaving me in obscurity, if you understand my meaning. The old light had evidently burned out.

My multimeter indicates that the replacement bulb is functional and has a secure connection to the holder. Inserting it into the unit's underside requires a push and a 90-degree rotation. I have completed this action, but I suspect it is not establishing proper contact, unless there is an internal malfunction.


Does anyone possess experience with this?

Thank you.

Is it an LED light bulb?...If that is the case, they are polarity sensitive, which may indicate that the orientation is incorrect.

Thank you, but the matter has been resolved. It is a typical filament bulb, but I needed to manipulate the small brass components that establish the wiping contact with the PCB. Ultimately, clarity emerged

Hello, do you know where I can obtain replacement bulbs? My current bulb is functioning, but the display lacks brightness. It is a 1.2W bulb, although it may require a higher wattage for improved illumination.

I purchased these items:

They lack intelligence, however they are preferable to having nothing. Furthermore, I would presume that increasing brightness without utilising LEDs necessitates higher power, resulting in greater heat generation.

[keithmerc220]

Your observation regarding the heat is valid. I may need to switch to LED; my current light functions but lacks brightness. If your experience is similar, I must either transition to LED or accept the current condition.

Thank you for the suggestion: I purchased some 1.2W LED counterparts on eBay, and they provide sufficient illumination to observe the surroundings without being very intense.
