Traction control switch

[biggles 1957]

Anyone got a 'spare' traction control switch for sale? Mine doesn't illuminate when I switch my lights on and all the other switches do. I got hold of a spare cruise control master switch thinking I might be able to swap the bulb over but it looks like the little led unit is part of the circuit board and not a straightforward swap without buying a new teeny weeny soldering iron!
Any advice welcome!:}
