Abstract
A headlamp for a vehicle includes a lamp housing having an opening portion; a discharge lamp removably contained in the lamp housing; and a lighting circuit unit, mounted in such a manner so as to cover the opening portion from a rear surface side of the lamp housing, for lighting the discharge lamp. A plug is separated from a cord connector when the lighting circuit unit is removed from the lamp housing. Thus, 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.
