Minor issue with A1 trailer towed by vans

[KrysEmlyn]

The small A1 L trailer that is towed by escort vans in traffic has a minor issue with the blinkers.
[ external image ]
As shown in the image, when the lead van has its left blinker on, both blinker flares are flashing on the trailer.
When the lead van has its right blinker on, only the vertex painted color for the right turn signal shows on the trailer model and no flare is visible for the right turn signal.

The affected model is the "hauled" variant of the "a1_l_trailer" trailer that the AI uses in traffic.
The model path for this trailer is "/vehicle/ai/event/a1_l/ai.pmd".
If you could please get this trailer fixed up so the turn signal flares are correct, that would be appreciated.
