Most of the green backlight in my switches were burnt out and I wanted an economical way to replace them. All the links I found for bulbs were defunct so I went on a search and found replacements.The majority of the switch backlights are a 3mm incandescent bulb with a green...wrapper.. on them, the only exception for that I ran into was the mirror switch which is a 5mm.
The bulbs I used are (amazon links below)
