Brake Lights just won’t STOP!

Took the Z out after a good while, and after parking I noticed the tail lights still on! Huh, it’s daytime and I don’t think I turned on the lights…

Maybe a fuse? A switch? Maybe the emergency brake switch… Oh, maybe the brake light switch on the brake pedal!

Then I found the breadcrumbs…

  
Ah little broken pieces, where do you come from…from what depths of Datsun dash do you petrified pieces of plastic purvey? 

This part looks about right judging from the clean ring of exposed metal…

  
So yesterday afternoon I’ve been parking it with a mail flyer wedged in there. But a quick trip to Home Depot did the job (I haven’t looked at the Datsun catalogs yet to reveal the REAL part). 

Picked up a simple metal hole plug, zinc plated, 3/8th inch – fits perfectly!

  
Make you think though – why even have a hole there? Why not just have the metal butt up against the switch? The switch itself is already on an adjustable screw, so it can’t be for micro adjustment reasons. But maybe it’s so that a cheaper part can be replaced instead of wearing out the switch with a hard piece of metal? I guess if the metal were wearing on the plastic trigger, eventually the trigger will break and the switch will need to be replaced. So instead, use an even cheaper replaceable part to wear out instead… 

What do you think?
