Lights and 3ds
Use a self-illuminated material on the headlight surfaces. If you want to cast
beams of light, create a couple of cones and apply self-illuminated material
combined with transparency/outside falloff.
When flat-mirror reflections don't work, it's usually because the material
exists in the object on two or more non-coplanar faces. Remember that it must
be applied to _only_ the coplanar faces of your rear-view mirror. To check, to
a Material Show, and take a look at which faces in the object contain the
flat-mirror material. If your face assignment is correct, check to make sure
that you've got specular color in the material, and that shininess is turned
up. If that doesn't do it, make sure you've got objects in the view of the
mirror.
