Title: Expensive hype
Product review: I fell for the hype and it was a mistake. Other reviewers will no doubt agree that these are short-lived bulbs and there is a reason for this. These bulbs are colored blue to *simulate* the HID look. Any color on the glass actually reduces output, so Sylvania uses an over-rated filament to get brighter light to compensate for the light absorbed by the coloring. Because federal laws are very specific about the output of headlights, Sylvania cannot use a filament that draws more current so the filament is burning overly hot and therefore has a shorter life. They same seems true for their uncolored X-Tra Vision bulbs. (Which may be the Silverstars without the color.) I tried those and they both burned out in less than a year, two weeks apart.I too have switched to GE bulbs and hope their bulbs are more durable.
Would you say this review depicts the product in a flattering or unflattering light?
