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.

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.

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.

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.

1992November

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.

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.

Production & sale of two-lamp GDHLs started

In four-lamp GDHLs, halogen bulbs were used for high beam, causing larger size and mixed colors. 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.
