The Bulbs are a brighter and show whiter light than regular bulbs. A few years ago when one of my headlight bulbs burnt out on high beam I bought two cheap 9004 bulbs thinking that all bulbs were the same. I replaced one of the bulbs and kept driving. When the other OEM bulb burnout several years later I knew I had a bulb replacement and swapped it out. Then I noticed either my night vision had gotten poorer or my lens on my Mercedes must have gotten oxidized by the UV light. When I checked the lens appeared to be glass. I kept driving around and almost had to use high-beam to see decently. I know something had to change. I choose Sylvania premium Silverstar headlight bulbs to give me the brightest view. I know these bulbs have a shorter life than standard bulbs but I that's the trade-off against standard bulbs. They are closer to Xenon bulbs in color but at the time that was $500 option at the time. If you are prepared to change your bulbs every 2 or 3 years then these bulbs are good fit.Read full review
