With a color temperature of 4,000 degrees Kelvin, these new SilverStar High Performance Halogen bulbs rival the light of pricey HID lights. They're available in 9004, 9005, 9006 and 9007 ST, while 9003s (to fit H4 lights) and sealed-beam versions will be out by September. These bulbs are very bright and also street-legal. Sure, you can buy cheap auxiliary lights for the same money, but the SilverStars are a much better deal if function is more important than looks. The 9004 ST bulbs seen here are rated at 65/45 watts, and it only takes one four-wheeler to change them.
