[0002]

2. Description of the Related Art Generally, an external HMSL provided outside a vehicle body of an automobile has an HMSL attached to a part of the vehicle body, and a connector is connected to a cord for electric wiring drawn from the HMSL. It is configured to connect to a connector of a cord on the power supply side of the vehicle body. For this reason, it is necessary to provide in advance a concave portion for housing the HMSL on the vehicle body side, or to provide a screw hole or the like for fixing the HMSL at the time of attaching the HMSL, which may complicate the vehicle body structure. In addition, there is a problem that the man-hour for attaching the HMSL is required. Further, since each of the HMSL and the vehicle body cord outlet has a cord insertion hole, various waterproof structures such as fitting a rubber bushing for waterproofing at this part are required.

[0003] In view of the above, the present applicant has previously disclosed in Japanese Patent Application No. 5-44375 a lamp holder provided integrally with a rim of a rear window glass, and a lamp unit is fitted to the lamp holder. A vehicular lamp capable of forming an HMSL has been proposed. That is, in this lamp, an LED as a light source is disposed in the lamp body, and this is sealed with a lens to form a lamp unit, and a part of the lamp unit is LE.
A connector electrically connected to D is provided. In addition, the lamp holder has a shape capable of accommodating the lamp unit, and a connector is provided in a part thereof, which penetrates the rim of the rear window glass and is connected to the power supply of the vehicle. Therefore, if the lamp unit is mounted on the lamp holder, the lamp unit can be held by the lamp holder by the engagement of the two, and at the same time, the two connectors are fitted together to enable electrical connection. Therefore, by providing the lamp holder integrally with the rim of the rear window glass, it is possible to avoid the complication of the vehicle body structure, and to simplify the waterproof structure by connecting the lamp unit and the lamp holder with a connector. .

[0004]

In such an HMSL proposed by the present applicant, the lamp unit comprises a lamp body,
Since the LED and lens are integrally configured, for example, when the LED stops operating due to its life, or when the connector becomes defective due to poor contact, or when the lens is broken, it is partially damaged Even in such a case, the entire lamp unit becomes defective and it is necessary to replace the lamp unit collectively. Further, when an HMSL having different light emission characteristics with different numbers or arrangements of LEDs is to be constructed, it is necessary to replace the entire lamp unit. For this reason, the maintenance price of the HMSL is increased, and parts that do not fail are also replaced, which is economically disadvantageous. It is an object of the present invention to provide an HM that enables a lamp unit to be partially replaced to effectively use parts.
It is to provide a vehicle lamp suitable for SL.
