How the hell have you managed to break your Omsi install so badly? What you're seeing there is the texture for a tree being used as the headlight bloom effect and some other random square texture as the actual light... that's most definitely not what they should look like or what they look like for everyone else. I think maybe you ought to do a verification of Omsi and/or check your graphics drivers/DirectX are not broken, because the wrong texture ending up being used is a quite major breakdown of code somewhere...Ai indicator lights are square
