You can put the small plastic thing which is the light under a pfSwitch. It
will have two nodes - one of them has a non-emmitive material, and the other
has an emmitive material. Then you use pfSwitchVal() to switch between the two.
If you want to create some light effect on the surfaces around the brake light
- you can turn a local light source on, when the brake is on. This local light
source is located in the position of the brake light.
