Philips X-tremeVision G-force is one of the brightest halogen bulbs for ultimate light performance. The bright white light of up to 3 500 Kelvin is whiter than standard headlamps. The Philips patented coating technology produces a more powerful light. Drivers can enjoy lighting performance among the brightest on offer and a much more comfortable night driving experience that helps them recognize obstacles and potential hazards earlier than most other halogen headlight lamps.
