Looking for H.I.D. bulbs but not willing to mortgage the house to get them? Well, these SilverStar H4666 bulbs deliver the intensity of H.I.D. systems but are priced for all us average Joes. Yes, brighter light is as easy as upgrading to these SilverStar bulbs. These Sylvania Silverstar H4666 bulbs deliver the whitest, brightest and sharpest halogen light that outperforms the competition, hands down. H4666 SilverStar bulbs deliver a white hot 4000k (Kelvin) which is far higher than other halogen bulbs on the market today. In fact a Kelvin rating this high is comparable to High Intensity Discharge (H.I.D.) systems found on many high end luxury vehicles today, considered the brightest lighting available for automotive applications. In addition, these Silverstar H4666 bulbs shine with a luminance up to 20% greater than other halogen bulbs. The amethyst blue coating, silver tip and sharp profile all conspire to create a dramatic high-end, crisp, clean look. Combine all these factors and the result is an entirely new night-time driving experience. All this means clearer visibility, safer travel and a high-end appearance. Silverstar bulbs deliver light up to 35% brighter, up to 30% more downroad visibility and up to 35% more sideroad visibility.

    Excellent Headlights - While They Last
    March 1, 2014
    Excellent visibility, crisp clean white light, great upgrade from stock, and give that extra margin of safety at night. However, as nice as they are, and as much as I really like them, I can't even get a year's lifespan out of them. And I put on less than 5000 miles/year. As such, I am in the process of converting over to an 8000K HID set, using aftermarket H4666 housings. The Silver Stars are still an excellent lamp, but the economics of frequent replacement were a little too steep. Maybe your car will do better with them.
    Pros:
    Excellent clear visibility, very pleasant and safe to drive with.
    Cons:
    The only Con for myself was the shorter lifespan. All else is very positive.
