Abstract
An advanced forward lighting system may be made with a lamp having a first filament and a second filament extending perpendicular to the first filament. The second filament is partially hidden rearward and above the first filament. A reflector forms a main beam from the first filament light and a right or left cast supplemental beam from the second filament light. The second filament's position minimizes glare, and enables a simple advanced forward lighting system from a single standard lamp fitting both right and left side reflectors.
