Summary:

Growing preferences for high-velocity motor vehicles lead a strong demand for headlamps with higher brightness and visibility. The low beam of conventional two-lamp system headlamps provides drivers poor visibility, since they are equipped with bulbs which have low-beam filament with relatively small power (35-45W) and luminous flux, compared to the high-power filament (65W) used for high-beam, in order to restrain the glare to on-coming drivers.The new halogen bulb with C-8/C-8 filament structure has such high power as 65/55W and when used in combination with a multi-focus reflector to compose a new 2-lamp system headlamp, it significantly increases the brightness of low-beam without causing much glare to the on-coming vehicles. At the same time, this new 2-lamp system headlamp is able to illuminate a broad area including the zone just in front of the vehicle without sacrificing the visibility of farthest area. Moreover, its novel structure promises us a variety of possible new applications as described hereunder
