Brake test switch

["ken hedges" <khedges@wkpower.com>]

Can anyone shed any light on the brake test lamp / switch on a 75B.

Mine needless to say is not working, but I also notice that is a different
type from my 70 parts (project) car.

The switch on the 75 does not move, and apears to be just to be a lamp, and
I would guess to monitor the the brake master cylinder.

Also with the weird spring arrangement that holds this lamp (switch) in the
dash, is there a easy way of removing the it.

Not a big problem, but I would like to get it working.
