Citan Dualiner - Mystery lighted rocker switch

[NDone]

I have just acquired a 66 plate Citan Dualiner 111.
Just above my right knee when driving, there is a small illuminated rocker switch on the bottom
part of the dashboard. Its a lighted yellow rocker switch.
It seems to have no discernible effect when switched on and off again.
Can anyone enlighten me as to what this switch is for ?
thanks in advance

Does it light up when you rock it..?

Sounds like it could possibly be an aftermarket addition for something the previous owner may have fitted... there are no switches shown in the owners manual on the right side, other than the main light switch

Do you have a photo?

Just checked and there is the ride height switch, but that is a kind of roller switch rather than an on/off type

thanks for that - its illuminated yellow when on but can't honestly see what it activates.
Maybe it opens the Bat cave or something. Thanks for the reply.

Ask the PO.
Trace the wires.

thanks think the PO was Network Rail. There is no beacon or even anywhere that looks like a beacon was attached.
Will take a look for the wires.
