DETAILED DESCRIPTION OF THE INVENTION

[0046] FIGS. 1 and 7 shows a preferred embodiment of an indicator lamp unit 3. The indicator lamp unit 3 includes a face 302 made of translucent material. The face 302 has an upside-down U-shaped indicia 310. A wall 303 of the indicator lamp unit 3 is present, which is connected to base 301. Base 301 can be attached to a part of an automobile. In one preferred embodiment, adhesive is placed on the rear of the base 301 for adhering the indicator lamp unit 3 to the automobile. In an alternate embodiment, a magnet is disposed on the rear of the base 301 for magnetically adhering the indicator lamp unit 3 to the automobile.
