hello - been in the middle east for a while and missed this post
In OZ it is illegal to have any other colour than Amber indicatator lights - However in W-OZ its permissible to use the Original Indicator lamps that the car was delivered with as long as said car is 30+yrs old.
Your rear back up lamps may have been disconnected - either at the firewall or on the tranny.
The general public get kind of crazy over here seeing my blinking red lights , a few dummies have even abused me for Non compliance - Idiots should put brain in gear before mouth !!!!
So if you have amber lens on your rear backup that's okay (dime a dozen at most OZ mustang suppliers) But i am sure Victoria is same as WA and therefore blinking red lights on a GT/CS is also okay cause its 30yrs old. Any other details please PM me as i am off to Peru tomorrow. Then onto LA ------------- HOPE TO CATCH a car show.
