[ZModeler] Siren Support

Hello, I am having an issues with my sirens? I am new to making a vehicle, when I exported it yesterday all the lights, etc worked, did some inside work to the truck and went to export it and now the lights aren't working but the environmentals are. I have attached a video to help yall see my issues.

The photos below are of what I see in game, the first photo shows nothing with the lights on, the second photo is so you can see the environmentals.

Thanks in advance!
