Well the lights mod works very well it seems to make the low beam lights a bit more bright but still have a proper distance.
The bigger detail is that now when other vehicles flash their brights at you especially from the behind or the sides you'll see the cab get brighter briefly(from the reflection in the mirrors if the vehicle is behind you). Cars will now flick their brights when they go to pass on a two lane road.
This mod was designed for version 1.6 so not sure if it will work as well on an older version.
