Second The second requirement for vehicle lights to work properly correctly is to use a separate UV layer for the lamp mask texture and proper tile offset of the mappings. Tilling Tiling is applied on the right side of the texture in the following order:
# <ol start="0"><li>original texture - front left side of vehicle</li># <li>first texture tile - front right side of vehicle</li># <li>second texture tile - rear left side of vehicle</li># <li>third texture tile - rear right side of vehicle</li># <li>fourth texture tile - middle of vehicle and DRL</li></ol>
# <ol start="0"><li>original texture - white color</li># <li>first texture tile - orange color</li></ol>
# <ol start="0"><li>first texture tile - red color of traffic light</li># <li>second texture tile - yellow color of traffic light</li># <li>third texture tile - green color of traffic light</li></ol>

Lamp system uses "lamp" material effect to visualize extra lit surfaces by second mask texture or by alpha channel of base texture. This system is used on vehicle lights, vehicle auxiliary lights and traffic lights.
For easy usage of lamp system Blender Tools has included [[Documentation/Tools/SCS Blender Tools/SCS Tools in Tool Shelf/Lamp Switcher & UV Tool|Lamp Switcher & UV Tool]] which will help you with UV mappings tiling and previewing of lit surfaces directly in Blender 3D viewport.

Vehicle lights uses use a second RGBA mask texture where from which each channel from RGBA color space defines a luminance mask for a particular type of the light:
* R - left blinker, right blinker
* A - positional
== Auxiliary lights ==
There is also possible to use two different colors for auxiliary lights with offsetting UV mappings for second mask texture. Tile offset here is also done on the right side of the texture:
== Traffic lights ==
Traffic lights don't use extra second mask texture as they are using alpha channel of base texture for proper lit of traffic lights. But they still use tile offset on UV mappings to properly lit up different color in traffic light. Tile offset here is done on right up side of the texture in the following order:
