Ugly enough to sink a ship, a DAF Torpedo tray truck from the 1960's.
Requires the AJS Traffic Library (kuid2:122285:901:2) as a dependency - it's on the DLS. As road traffic, you will be able to adjust its height above the road. Nightmode lighting times can be controlled and the lights can be made to switch on in heavy rain or snow. To access traffic settings for this vehicle, place it on the ground in Surveyor, click on the Properties (?) button in the Scenery tab, and then on the vehicle. Note that when the car is static scenery, nightmode will not be active.
