Automotive technology has changed a lot since the release of the Camaro, and headlights (a.k.a. headlamps) are a prime example. Through most of the '70s, American cars still featured incandescent sealed-beam lights. When these lights burned out, the entire unit had to be replaced, rather than simply inserting a new bulb into a reusable housing. Thankfully, several newer types of headlight were developed in the following decades, including halogen, HID, and LED. Today, we'll briefly go over each type and its advantages in this Camaro headlight upgrade guide.
