My car is a 2005 Subaru Impreza RV, and has asymmetrical tail lights, in particular with one 'round' light being clear, and the other red. Exactly like the below picture. (Same model, not my car pictured).
The lights on this side had cracked, and thus the plastic had been damaged over the years by water and so I ordered a replacement for the right side only. However, the 'circle' light on the replacement was clear, like on the left side (I assume the part I order may have come from a left-hand drive market, where the lights were reversed). This red circle light was the rear-fog light, where the left, clear circle light was not (Either a running light or reverse light, can't quite remember.) My question is, whether it is legal to have my rear fog light be clear, and not red. I never use it, so I'm more worried about a cop assuming that it is not a discoloured rear fog light, but a broken reverse/running light. Would I get into trouble over this? I live in the state of New South Wales, Australia.
