<p>PURPOSE:To improve easiness in visual checking laterally and fore and aft by furnishing an upper, a lower and a side rib protrudingly on a globe-shaped inner lens in such a way as consolidated, and thereby enlarging the illuminating area of inner lens when it is lighted. CONSTITUTION:An electric bulb supported in a lamp chamber composed of a lamp body and an outer lens is enclosed by an inner lens (umber globe) 11 in a globe form. In a single piece, are furnished a side rib 15, a lower rib 14, and an upper rib 13 formed greater than the body 12 of the inner lens. When the electric bulb is lighted and the inner lens body 12 is illuminated, these ribs 13, 14, 15 are illuminated simultaneously, and thereby the illumination area is enlarged even the inner lens is embodied in a small size, which shoud enhance the easiness in visual checking.</p> |
