Rear Marker Lights

[rallyvan]

This is the first time I have worked on a HQ-WB series Holden and the rear tail lights work a bit differently to what I am use to. Usually there is a dedicated clear reverse light but on the HZ it appears as though the orange rear indicator lights up when reverse is engaged. I assume that the orange red lens in the rear quarter panel works the same as a clearance light on a truck or trailer and light in the rear quarter should be on at the same time as rear tail light. Can some one confirm whether my thinking is correct?

The rear marker/relay orange light illuminates at the same time the corresponding rear blinker/indicator lamp illuminates. So yeah, they (both sides) should illuminate when the vehicle is in reverse.
