No Halogen can come close to the HID Xenon lighting provided by MB or the aftermarket. Any Halogen that illuminates the road as well as a HID will probably not be legal. Halogens modified to give a "blueish" light will actually be worse than regular Halogens. The reason being Halogens do not emit much light in the blue spectrum. Since you are only letting the blue light through, you are weakening the Halogen light you do have. The HID Xenon's look "blue" from the outside but when driving a car equipped with them, the illumination looks pure white. Either get HID Xenon's and do it right, or use what you have. Higher wattage or otherwise modified Halogen bulbs wont give you HID visibility and may get you in trouble with the DOT. Once instance where you do get what you pay for. Search the Shop Forum records regarding HID lighting and HID conversions.

Hope this helps...Lee
