[TR] Reversing light switch.

[David Brister]

Having just removed the gearbox and driveshaft cover for the first time in 
over 20 years, I thought it would be a good time to wire my reversing light 
to the appropriate switch. (Something I overlooked long ago. There was the 
remains of a reversing light under the rear bumper then but I removed it and 
fitted two of those beehive clear glass lights to the boot lid, controlled 
by an on/off switch under the dash..Non standard but at least you can see 
behind you.). So I assume there must have been an automatic switch on the 
gearbox.
Now I can't find any reference in any of my books to a reversing light 
switch although it is shown as an optional extra on the wiring diagrams. My 
gearbox just has the two overdrive enabling switches on the top, all wired 
according to the book.
Can anyone remember if there is or ever was such a switch fitted to a TR4A. 
If so could it be retro fitted?

Thanks,
