Abstract
A four lamp type headlamp in which two headlamp units each having two lighting fixtures are symmetrically arranged on left and right front end sides of a vehicle such that distribution light of running (high) beams and distribution light of pass-each-other (low) beam can be switched with each other. One of the two lighting fixtures in each headlamp unit is a projector type fixture and is formed to be switchable between the distribution light of the pass-each-other beams and the running beams. The other lighting fixture in each headlamp unit is always lit and forms a portion of the pass-each-other beams. During driving with the running beams, one lighting fixture in each headlamp unit provides the running beams while the other lighting fixture in each headlamp unit remains in an 'ON' state (lit). When driving with the pass-each-other beams, distribution light for the pass-each-other beams is provided by light from the four lighting fixtures.
