<p>PURPOSE: To make the reflection prism of an inner housing appear to continue to the prism of a cap. CONSTITUTION: A prism 41, which appears to continue to the reflection prism 30 of an inner housing 3 as viewed from a lens 2, is provided in a cap 4. As a result, when the inside of a lamp housing 14 is viewed from the lens 2 while a light-source bulb 5 is not turned on, the reflection prism 30 of the inner housing 3 appears to continue to the prism 41 of the cap 4.</p> |
