The invention involves application of a luster coating to the exterior of a glass lamp capsule envelope to obtain a blue coloration of the transmitted light. The result is a higher color temperature light source that is commercially preferred. The preferred blue luster is formed from a coating solution containing organometallic components and solvent, that is heat treated in an oxidizing atmosphere to form a gold containing bismuth-titanium oxide material. The filament is adjusted to yield the overall necessary number of lumens. The blue luster tinted automobile lamp capsule is a durable, and yields the proper number of lumens with little or no increase in glare. The blue luster tinted lamp capsule is therefore compliant with legal standards.

An amber vehicle lamp having a lamp bulb, and an amber coating including a clear silicone-polyester resin, and colorants including red iron oxide, and a yellow anthraquinone. The amber coating may further include a silane coupling agent. The amber vehicle lamp provides an amber color meeting ECE specifications, and having a coating durability of 96 percent of color at 70 percent of the rated lamp life. The colorants have a particle size of less than 0.01 microns providing a substantially clear amber colored bulb.

A long life, two filament tungsten halogen lamp having light transmissive envelope, a first filament with a first lead, second lead, filament coil; a second similar filament, and a fill material is disclosed. The filament coil has an increased wire weight, increased over what is commonly used. The fill material comprises a halogen for the tungsten halogen cycle, a getter, and the remainder is approximately equal portions of krypton and xenon. The basic life improvement comes from the heavier tungsten wire weight, combined with the heavier molecular weight of xenon and krypton. The new filament and fill gives a two filament tungsten halogen lamp yielding substantially longer lamp life.

A high-pressure sodium arc discharge lamp having a novel arc tube support member which provides a secure mechanical and electrical connection and does not require welding between the support member and the arc tube lead wire or feedthrough. The support member may be adapted for mounting a single arc tube or two arc tubes within the outer envelope. The feedthrough of each arc tube is inserted into an aperture in the support member such that a secure interference fit is achieved. The interference fit is similar to the fastening of a threadless nut. In a preferred embodiment, the support member has a first planar surface having one or more apertures therein and two second planar surfaces substantially perpendicular to the first planar surface; each second planar surface has a protruding leg by which the support member may be mounted on the internal lamp frame. Several alternative designs are disclosed wherein, for example, the aperture may be circular or rectangular, the aperture may or may not have opposing tabs, and the cross section of the arc tube lead wire or feedthrough disposed within the aperture may be circular or rectangular.
