ETS2 - Headlight Options

This mod includes Halogen, LED, & Xenon headlight options for all SCS trucks that have headlight options(*) in the store {this mod does not include SCS trucks that don't have headlight options}.

NOTES:
- Some trucks don't have a Halogen options because Europe is banning halogen bulbs.
- 1.49 release removed some trucks from their dealers. Headlight options are available for those trucks when you buy them used.

(**) The following codes define the various headlight options compared to SCS defaults:
[L;H] = Low beams shine wider and longer; High beams shine longer ('HiLo'),
[L>H] = Low and High beams both shine wider and longer ('Combd'),
[H] = Low beams shine the same ; High beams shine longer ('Hi only').

New: coordinated beam_color
