Headlight upgrade 1.40

This mod widens low beams and lengthens high beams for all v1.40 SCS ATS trucks. (Selected mod trucks will come later.)

You can also choose between Halogen and LED headlights at the Cascadia, Anthem, and 49X Truck Dealers.
(LED headlights are whiter [and slightly brighter] than default Halogen headlights.)
