6x6 Land Rover Perentie | High level light fail

Having finally got sick of not knowing why my trailer and high level rear lights were not working properly I decided to dive into the less than optimal wiring in the 6x6 Land Rover Perentie Ambulance.

I absolutely love the 12V light tester, I use mine all the time!

yeah one of those things I think should come standard with every vehicle, that and a cheap multimeter.

Are they required by law? I would suggest not.

according to vicroads, any light that is fitted must be functional, and any functional light must comply with ADR.
