Paystar 5070 has no rooflights, never. A bumper with some additional ones comes pretty late at I think Level 7 and driving in the night with stock lights to that point is a pain in the ass. All other trucks and all scouts get some "light addons".
The mod F5070 has stolen rooflights from the ANK. See
Thats it. Collision checks with horns, looks cool, works perfectly, I would be happy. By the way, the slightly better engine option in the mod makes the thing a bit better with trailer. Its still not Voron level (far away from it), but on the OK side.
