i have had this switch in my vw since owning it , i have no idea what it is for and it is not wired to anything , so have taken it out of the dash placing and i wondered if anyone could tell me about it - It looks like this No wire connector screws but i think i could find some of those if it is a part that should be working . when i took it i apart found it has a bulb fitting with bulb in it , note the brass perforated front plate . Any ideas anyone ?
Why do you call it a switch it looks like a warning/indicator lamp from here. Where about in your bus was i t mounted.
Could be anything. As above, as it doesn't have spades, it's some aftermarket thing. Folks fit all sorts to their busses.
