Over the past 20 years, automotive technology has increased drastically.

Essentially, we've moved from knobs and switches to touchscreens to voice activation to gestures today. But, that's only one component of it.

When you consider how far powertrains have come along as well as things like safety technology, we're really living in a Jetsons-like age.

While I am more than aware of the difference between standard halogen lights and xenons, I always wanted to learn a bit more when it came to LEDs as well as the latest and greatest technology found in laser lights.

If you're like me, now's the time to cross that road.

Our friends at CAR magazine recently published a piece that serves as a primer. I learned a thing or two and figured the Spies would appreciate this 101 knowledge.
