US tail lights are not compliant here in Australia.
Our grands came with a reversing light, an amber indicator light and a combination tail stop light.
The US (WK) doesn't have a yellow indicator and is wired differently so the red brake stop lamp flash's, the clear section is the reversing light.
Aus compliance requires an amber/yellow turn signal (since late 70's I think).
In theory you could rewire the reversing clear section to be the indicator but you would have to fit a clear/white reversing light at the rear of the Grand to comply with Aus law.
By the looks of it if Jeep have stopped making WH tail lights something like this will be our only option.
