@GeorgeAlex Thanks for the information. Initially, I was planning to create a more comprehensive mod, such as setting appropriate beam patterns considering each truck's headlight technology. At some point, I decided it would be a very time-consuming task and gave up on that project. However, I can use your information if I decide to revisit the project. I hope SCS does something about headlights before I do :D

I am a truck driver so I can help you out a little bit with some info. The only trucks which use projector lights are Renault Premium (Halogen), Range T (Halogen and Xenon), Iveco Stralis ( Halogen), Mercedes (Halogen and Xenon. Now for the MP5 they use Halogen reflector and LED projector) and Volvo FH 2012 (Halogen and Xenon). The rest of them all use reflector LED. Hope this will help you to create an accurate mod.
