Interior Light 1.33.x

I fixed this modification a long time ago for personal use, but decided to share.

Refreshment is put in the workshop in place of flashing beacons! It has 7 colors:
WHITE
GREEN
BLUE
ORANGE
BLUE
RED
YELLOW
Available for purchase from level 0.

Highlighting is available for trucks:

DAF XF 105
DAF XF Euro 6
Iveco Hiway (does not work correctly, more illuminates the bed than the dashboard)
Iveco Stralis (does not work correctly, more illuminates the bed than the dashboard)
Man TGX
Mercedes Actros MP3 (not for all cabs)
Mercedes Actros MP4 (does not work correctly, more illuminates the bed than the dashboard)
Renault Magnum (does not work correctly, more illuminates the bed than the dashboard)
Renault Premium (does not work due to the lack of flashing beacons of the brand of this truck)
Scania R
Scania S
Scania R 2016
Scania S 2016
Volvo FH 16
Volvo FH 2012

Modification work on versions from 1.27 to 1.33 is possible.
In the graphics settings you should have a tick in the item: Additional lighting. If you do not do this – the backlight will not turn on! The backlight is turned on and off by single pressing on the activation key of flashing beacons, by default, the “O” key.
