Lighting for Your Safety Koito

Expanding Period 1981 -

1982 November
Production & sale of halogen bulbs for automobiles started
KOITO was depending on imported halogen bulbs, but since recognizing the importance of having own light source,  KOITO started to manufacture them in-house. After overcoming initial failures due to difficulties in glass processing, KOITO succeeded in mass-producing the C-6 type in April 1981 which it began selling in November 1982. 1983 April
North American Lighting, Inc. (NAL) established in Illinois, USA 1984 May
Swiss franc-denominated, privately-placed, unsecured convertible bonds issued 
(50 million Swiss francs) 1984 April
Production & sale of the world’s first all-plastic uniquely shaped headlamps started
To reduce the weight and improve designability, KOITO researched ways to manufacture plastic headlamps using technologies adopted in the development of plastic signal lamps. In 1981, KOITO developed a plastic lens as well as a BMC reflector that has high thermal resistance and molding precision. In December 1984, the world’s first all-plastic uniquely shaped headlamp made by KOITO was used in the Toyota Soarer. 1984 December

Projector headlamp commercialized
To reduce the headlamp width and to slant the outer lens to improve vehicles’ aerodynamic properties, KOITO developed a projector headlamp, which is a new type of lamp that distributes light with a combination of a composite elliptical reflector and a convex lens. This product started to be used in the Toyota Sera in March 1990. 1992 May
Fujikawa Tooling Plant opened in Shizuoka, Japan 1992 June
Four-lamp headlamps for racing developed
At the request of Toyota Motor, KOITO developed four-lamp headlamps for racing; these are brighter than competitors’ headlamps and produce an even light distribution. The weight was also reduced by using carbon. In June 1992, these products were used in the Toyota TS-020 and 92C-V that participated in the 24 Hours of Le Mans race. 1992 November
Supply of freeform surface reflector headlamps started
In response to further lamp design needs, KOITO designed and manufactured a freeform surface reflector necessary for transparent lenses (light distribution is controlled by steps provided on the reflector). This was achieved thanks to high design precision, and the headlamp started to be used in the Mitsubishi Eterna in November 1992. 1993 February
NAL’s Technical Center opened in Michigan, USA 1996 May
Capital participation in Britax Vega Ltd. (BVL) of UK 1996 July
Production & sale of discharge headlamps (GDHLs) started
A GDHL is a light source that utilizes arc discharge between electrodes and was considered to produce more light, and have long life and high energy efficiency. As the next-generation lamp, KOITO developed the lamp as well as a control circuit called “ballast”, which were used in the Nissan Terrano and the Toyota Mark II in 1996. 1997 March

To solve these problems, KOITO developed and mass-produced Japan’s first two-lamp GDHL, which allows switching between high beam and low beam with a single bulb by using a movable shield for light distribution. 2001
Production & sale of LED signal lamps started
Seeing the effectiveness of using LEDs in signal lamps for their energy- and space-efficiency as well as long life, KOITO developed and successfully commercialized LED signal lamps using a pressure-welded wiring system. These lamps started to be used in the Nissan Skyline in 2001. 2001 March
