Dart Reverse Lights

[Vicki Mayer <kimba124@xxxxxxxxxxxxx>]

Help!

My 62 Dart came from the factory with no reverse lights.  Part of my
restoration is adding them, for safety reasons.  Does anybody know how to
activate the reverse lights with a manual pushbutton transmission?  Is there
a micro-switch? A cable?  A button?  A what-cha-ma-callit that either exists
or I can buy and install?

And where can I find the globe and harness for them?

Thanks everyone!
