I remember watching a set of black & white post processing tutorials by David Nightingale of Chromasia. In one of them he produced a very dramatic image of a car headlight. Until then, I had not paid much attention to modern car headlights, but they are fascinating.
For a while now, when I have some time to kill before an appointment, I look for car headlights to photograph with my iPhone. It takes some post processing to turn the images into dramatic ones, but there are plenty of apps for that. I personally use the Camera+ app on my smartphone. In case I feel the need to add a texture or film effect, I use Mextures.
