Re-wiring rear lighte for compliance.

(1/3) > >>

Scott:
One of my remaining tasks, that has been put off again and again is rewiring the tail lights so that I have amber indicators.  The same wire powers up for the brake light and indicator, which both use the same filament in the bulb.  I have tried reading the wiring diagram, but I can't work out where abouts these become two separate wires that I can run to different bulbs.

Can anyone provide a hint, or point me in the right direction? I'm good with a multimeter and basic electronics, just bad with wiring diagrams :mmm:

Cheers
Scott

RHD.68.l89:
The brake signal is fed to the indicator switch in the column. when the indicators are off it it is fed to both the tail lights. when you operate the indicators the flashing signal is fed to the appropriate bulb while disconnecting the brake signal from that bulb.
disconnect the brake switch signal from the indicator connector and feed it down the back. If you are using the reversing socket to house an amber bullb swap the Indicator/Brake line to the inner housing and run the new brake line to both the outer housings. Reverse signal can be either switched in to replace the brake (giving amber reversing and allowing you to use the reversing wire to send the brake signal) or fed to new white lights mounted under the bumper.

I have been told by the inspectors at Vicroads AND the engineer that's going to be doing my ticket that because of the age of my car (1970) that i do not have to alter the rear lenses. Your car should be in the same category.

If I were you I'd be looking into it a bit more and making a few phone calls.

The side markers are a different story - eiter pull te globes like most do or you can try rewiring them as indicators which is what I'll be attempting.

RHD.68.l89:
Depends on the ADRs. I know the ADRs came in 1/1/69 so vehicles built before that date do not require amber front and rear indicators. Supposedly after that date they do. FC holdens had a combined indicator/brake lamp so it was legal at some point.

Scott:
Thanks for that RHD.68.  I'll have to get under the dash and play around.
My car is a 73, so I definitely need amber rear indicators. A few years earlier and the red was passable.  Not a big issue really.  I have some white lights to incorporate for reversing lights and a clever scheme to try make it look good too... Whether or not it works is another thing though.
