Preview of a simple scene using Mental Ray Glare and Glow Shaders in Studio 3D MAX to mimic the glare/flaring from a Halogen light with patterned lens and a powerful blue-tint Xenon light.
For a detailed look into this lighting setup, please go to this thread on CG-Cars.com (free registration required) where I explain the textures (NOTE: this was done in Max7 - newer versions will handle this differently - I may update this section to cover that):
The Flash animation below shows the two lights with glare/streak effects as the camera sweeps around - also used is the puddle texture that is explained in detail in the Puddle Texture section :

Preview Images showing the same scene as above with the addition of an image to control streaking:
Mental Ray Glare (streak) used for effect on the lights - with the Puddle Texture
The Xenon light has a stronger setting for the Glare shader and is effected more by streaking
Looking straight on to the lights sources - the Halogen light is correctly focusing the light directly into the camera
