312D 4x4 Mystery light stuck on. Can anyone tell me what it is?

On my 312D I have a mystery light stuck on on the dash. Can anyone tell me what it is?
Its been on for years and never caused any issues but I am trying to trouble shoot and would love to work it out.
The light appears on the far right of the dash light warning area.
Any ideas?
The image is the last image on the right of the dash with the wheels picture.

I have the 312D 4x4 Sprinter 2000 model

No its not a joke.
The 4wd light its the one next to it. 2nd yellow light from the right. I know what the 4wd light looks like ;)
I've owned the vehicle for 8 years and this light has always been on.
When I engage 4wd the other light (2nd yellow light from the right) come on. When I disengage it it goes off.
The light on the far right however stays on all the time.

The second light is the diff lock, the end light is FWD If its not then you have a wiring fault. you can sort this out by pulling the plug on the diff and the transfer case. Eric.
The light is for an optional power take off, the light staying on is probably the globe for the srs, when i put mine over the pits the srs light was on so i swapped it over with the 4x4 light, and left the srs light behind the dash, has worked ok only do not have 4x4 light, nuccan nuccan
