After my wife complained about the headlights on our 2013 Chevy Volt, I immediately looked for LED replacement bulbs. Considering there is such a wide price range, I chose a Volt bulb that was inexpensive and well reviewed. It was a plug and play installation. It took me less than 10 minutes to complete. As you can see in the before and after photos, the light is 18 degrees brighter than before. The high beam setting is great as well. I highly recommend these bulbs!
