Head lamp device

摘要

A head lamp device (1) has a connector guide (4) which enables a feeder connector (20) to be insertable into a socket (12), only rotating the bulb (10) to a fixed position (FX) specified. In this manner, a feeder connector (20) is not insertable in a socket (12) when the bulb is not in the fixed position (FX) so that even inexperienced operators can surely enforce the replacement of the bulb (10), therefore, a specified light distribution can be surely obtained.
