The first dual-filament halogen bulb to produce both a low and a high beam, the H4 (60/55 W @ 12 V, 1650/1000 lm ±15% @ 13.2 V), [93] was released in 1971 [13] and quickly became the predominant headlamp bulb throughout the world except in the United States, where the H4 is still not legal for automotive use.
In North America, the 2000 Cadillac Deville was the first passenger car with LED taillights. [144] The 2002 Kia Opirus was an early adopter of LED front turn signals. [ 145 ] The 2007 Audi R8 used two strips of optically focused high-intensity LEDs for its daytime running lights.
R20 — Headlamps emitting an asymmetrical passing beam and/or a driving beam and equipped with halogen double-filament H4 bulbs (superseded by R112, but still valid for existing approvals) R31 — Halogen sealed beam headlamps emitting an asymmetrical passing beam and/or a driving beam; R45 — Headlamp cleaners
Under ECE regulations, H1 lamps are required to emit white or selective yellow light. [1] U.S. regulations require H1 lamps to emit white light. [2] Under both ECE and U.S. specifications, the allowable range of white light is quite large; some H1 lamps have a slight blue or yellow tint to the glass yet still produce light legally acceptable under the requirement for white light.
To reduce unintentional ultraviolet (UV) exposure, and to contain hot bulb fragments in the event of explosive bulb failure, general-purpose lamps usually have a UV-absorbing glass filter over or around the bulb. Alternatively, lamp bulbs may be doped or coated to filter out the UV radiation. With adequate filtering, a halogen lamp exposes ...
