Hello, I installed a police vehicle (policet) and in the game you do not see the emergency lights, someone help me?

 

 

Did you make sure to install the visuals.dat to this path in OpenIV:
"mods/update/update.rpf/common/data"

 

You can also try using a trainer to remove the tint off of the car in game. Some cars have tint auto applied and it can dim the lights to an almost un-see-able brightness.
