PIAA bulbs combine Xtreme technology with a high power XTRA halogen bulb for increased performance. This allows the bulb to emit a beam of light that is whiter and brighter than standard bulbs of the same style while using less amperage. PIAA Xtreme bulbs approach the brightness and intensity of High Intensity Discharge (HID) lamps at a fraction of the cost. These bulbs project a nice sharp beam in a cool white / blue hue that reduces eye-strain and improves contrast. They are SAE and DOT certification,.
