**Vehicle lamp.** This invention describes an attachment groove in a lamp body whose outer peripheral wall branches into two walls near one end of the front lens. The inner branch wall can have a smaller opening angle to help prevent sealant from escaping onto its outer surface as an attachment leg is inserted. The outer branch wall can have a larger opening angle to accommodate lamp-design requirements.

**Vehicular lamp.** This design combines a red lens over a red light-emitting portion, clear lenses over amber and clear light-emitting portions, and a smoky dummy lens around the light-emitting portions. An amber bulb and amber paint on the reflector help produce amber illumination through the clear lens, while making the amber section appear uniformly luminous.
