If you ever have to do a report on automotive headlights, you'll discover that the first lights were fueled by either oil or acetylene. We owe the guys at Cadillac a big thank you for figuring out a way to use electric lights back in 1912. This of course, paved the way for modern Chevy Caprice headlight bulbs, like halogen Caprice headlight bulbs. These bulbs put out an incredibly bright light that does a fantastic job illuminating the roadway. And, halogen Chevy Caprice headlight bulbs have the advantage of holding their brightness through their product life.
