A while ago, I returned to LSPDFR, installed mods, vehicles, and other stuff, and everything was working. It was back in January. Yesterday, after this short break, I returned and wanted to play. I got into the patrol car, pressed J, and what happened? Nothing happened. The sirens sound, but the police lights don't. Depending on the vehicle, some lights don't work at all, while others only work halfway. I don't know what's going on—any suggestions?
