I just repalced my back up light switch on a 84 manual westy after noticing
the previous wasn't working but now I have a new problem.   While I'm
shifting a get a flicker in the back up lights between gears, I'm not too
sure if the old one was like this or not.  Any suggestions?

The replacement wasn't an exact match, same depth just a different plug for
the 2 wires.

Thanks,
