hey all , iam in a sticky situation my screen on my climate control wont work, but it all still works, it seems like a bulb and was wondering what kind they are so i can swap them or even put a LED in its place

ED right ?
Standard wedge globe, but you have to pull the thing apart to replace it, and yes you could add some leds instead if you wish.

Oh and to check if it works so to speak, in the dark, shine a torch in the front of it, you will then be able to read the display.
