[Mgs] MGB Question

[Hans Duinhoven]

The gismo light has in fact two functions:
1 = Brake differential warning indicator lamp
2 = Pressing this unit activates a test of this lamp

1 is activated, if there occurs a pressure difference between the two 
hydraulic brake circuits.
This happens when one circuit is leaky.
In my 1971 BGT the switch is defect and NLA - so there is no function.

The white handle does not ring a bell.

Cheers,

Hans
