THIS PRODUCT IS A PRODUCT THAT WILL BE PREFERRED BY XENON DRIVERS. WHEN A STANDARD XENON BULB BLOWS UP AND IS REPLACED, IT REQUIRES SOME TIME (100 HOURS, APPROXIMATELY 3.5-4 MONTHS) TO PRODUCE WHITE LIGHT. SINCE THIS PRODUCT IS NOT WELL KNOWN IN THE MARKET, THE DRIVER HAS TO RISK HAVING DIFFERENT COLORED HEADLIGHTS DURING THESE 4 MONTHS. THIS PHILIPS PRODUCT DOES NOT HAVE AN ALTERNATIVE, PROVIDES WHITE LIGHT IMMEDIATELY AND IS ONLY 20% EXPENSIVE THAN NORMAL XENON.
