摘要：
A red automotive incandescent lamp having a sealed lamp envelope formed from an amber glass, a pair of filaments located within the lamp envelope, and a red pigmented coating applied to an external surface of the envelope. The amber glass provides initial filtering of the shorter wavelengths of visible light, so that the red pigment has to filter out less light and therefore can be made less opaque. As a result, the lamp produces the desired red colored light at a total light output that meets applicable SAE and ECE requirements for automotive lamps.
