Abstract
Abstract A vehicle lamp device for use as a combination clearance and side-marker lamp in which coloration of a clear clearance lens by light reflected from the colored marker lens is inhibited. The lamp device includes a lamp body, a clearance lens covering the lamp body, a marker lens covering an outside opening portion of the lamp body with the marker lens being connected at one end to the clearance lens and colored in a predetermined color such as amber, a bulb disposed inside the lamp device body, and a reflection surface for reflecting light reflected from the marker lens again toward the marker lens formed on an inner surface of a side wall opposed to the outside opening portion of the lamp device body. Also, front and rear surfaces of a lens attaching portion formed on the side surface of the clearance lens may be made light diffusing.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
112 words
A vehicle lamp device comprising: a lamp body, a transparent clearance lens covering a front opening portion of said lamp body; a marker lens covering a side opening portion of said lamp body, said marker lens being connected at one end to said clearance lens and colored in a predetermined color; a bulb disposed inside said lamp device body; and a reflection surface for reflecting light reflected from said marker lens back toward said marker lens formed on an inner surface of a side wall opposed to said side opening portion of said lamp device body, whereby light reflect from said marker lens is prevented from being reflected toward said clearance lens.
