Reverse Light Switch:

Early Holdens had no Reverse Switch as standard. A Reverse Switch was an option for EK - HR. The Blinker Assembly provided Reverse Light support by integrating the  Reverse lighting through the Blinker Light and Blinker Switch.

Reverse Light:

To indicate that a car is reversing and to illuminate the area behind the car, reverse lights are fitted. Originally these were activated by a driver operated switch but later this switch was operated by the gear lever to bring the lights on automatically when reverse gear was engaged.

Wiring:

In Automatics, the Reverse Light Switch is built into the Neutral Safety Switch.The light green and dark green Wires for the Reverse lights are connected to the right hand 2 Contacts.The dark green Wire comes from the Fuse Panel and the light green Wire goes to the Blinker Switch.The wire colours are the same for Manuals.

Note the Adjusting Nut and Stud. When in Reverse the Selector Lever moves closer to the Firewall than when in 2nd. The Nut allows you to position the Switch as near to the Firewall as necessary to prevent activation in 2nd Gear. Click to Enlargen. Photo by HRAmbo.
 
If this adjustment isn't made correctly the Reverse lights will come on in 2nd Gear. Click to Enlargen. Photo by HRAmbo.
