[TR] TR3A Brake light switch

[Bob]

Alex,

I use DOT 4 on my 3 and DOT 5 on my 4 and have never had a problem with the 
switch. My lights go on with just a little tap. 

The switches on both cars are original Lucas.

If you need a Lucas spare to try out let me know and I can find one in the 
parts bin. I am sure I have both the screw and spade versions somewhere.

But if it was me and the switch stopped working,  I would install a 4A type 
switch and just run the wires back to the switch by just attaching them to the 
existing harness and run through the firewall and back so not to mess up the 
engine bay.
