Upgrading the frontal lighting system of car with E46 HID is never a difficult decision for most people, especially for those who desire greater luminous efficacy while driving on the road. High-Intensity Discharge headlamps produce more powerful beams at the same amount of energy that tungsten-halogen lamps use. That is why the bulb size of HIDs is fairly smaller than the conventional headlights. This is to compensate for its very high illumination, which is prohibited in some places of the US and Europe.
Although E46 HID are great custom parts, their use might be restricted. While its high-intensity lights are beneficial to the person driving on dark roads, it may be too glaring for oncoming traffic. One option to resolve this is to get a projector HID headlight that produces asymmetrical low beam patterns. With this one in the package, car owners will have sufficient lateral and frontal visibility without troubling the other drivers on the opposite side of the road.
Aftermarket companies that offer reasonably priced E46 HID abound in the Internet. People can always approach the manufacturer of their cars for options, so that they can be assured of quality. Nonetheless, there are good deals that can be explored online and on site. Experienced motorists and customizers can be approached for referrals.
