Powerful light from Xenon HID bulb offers maximum safety
Xenon HID (High Intensity Discharge) lamps offer twice as much light* for safer driving in all conditions. The intense white light produced by the Xenon HID lamps is comparable to daylight. Studies have demonstrated that xenon automotive lighting helps drivers to concentrate on the road and to distinguish obstacles and road signs much faster than traditional lamps. *compared to standard halogen bulbs
Philips car lamps are highly resistant against humidity
Only a burning bulb made of quartz glass (filament 2650°c, glass 800°c) can resist thermal shocks : such as, if a drop of cold water touches the hot bulb, when you drive through water with a broken headlight unit.
