Headlamp for vehicle

摘要

A headlamp 1 for a vehicle includes a lamp housing 2 having an opening portion 2a; a discharge lamp 3 removably contained in the lamp housing 2; and a lighting circuit unit 5, mounted in such a manner as to cover the opening portion 2a from a rear surface side of the lamp housing 2, for lighting the discharge lamp 4, wherein a plug 6b is separated from a cord connector 6a when the lighting circuit unit 5 is removed from the lamp housing 2. When the work of removing the lighting circuit unit is completed, the plug is necessarily separated from the cord connector, to thereby cut off the power supply to the lighting circuit unit.
