I use to ride a school bus it was a 2016 model of a Tomas and during my time in middle school usually at winter you can tell that the bus was heading your way since those amber strobe lights were bright enough as the police strobe bars. this comes to that I think brightening it up would be great as right now they are dull. another thing is if another model of the school bus was created such named the old reliable substitute. which is a similar model to that of the Beamng school bus but worn down faded colors of its yellow and the looks of the musty tan seats with a bit of rust to it.
