List of automotive light bulb types

Light bulbs for automobiles are made in several standardized series. Bulbs used for headlamps, turn signals and brake lamps may be required to comply with international and national regulations governing the types of lamps used. Other automotive lighting applications such as auxiliary lamps or interior lighting may not be regulated, but common types are used by many automotive manufacturers.

International

The World Forum for Harmonization of Vehicle Regulations (ECE Regulations) develops and maintains international-consensus UN Regulations on light sources acceptable for use in lamps on vehicles and trailers type-approved for use in countries that recognise the UN Regulations. These include Regulation 37, which contains specifications for filament lamps, and Regulation 99 and its addenda which covers light sources for high-intensity discharge headlamps. Some UN-approved bulb types are also permitted by some other regulations, such as those of the United States or of Japan, though Japan has begun supplanting the former Japanese national regulations with the international UN regulations.

H7 (monogram)

H7 was the monogram of the Norwegian head of state, King Haakon VII, who reigned from 1905 to 1957. When Germany invaded Norway in 1940 as a part of World War II, the royal family fled the country and Haakon VII later spearheaded the Norwegian resistance in-exile in the United Kingdom. H7 became one of several symbols used by the Norwegian populace to mark solidarity with and loyalty to the King, and adherence to the Norwegian resistance movement.

World War II

According to Minister of Foreign Affairs Bjørn Tore Godal, speaking at the 50th anniversary for Victory in Europe Day, Norway was the only country in which the initials of the head of state became a resistance symbol. The monogram, with H superimposed on 7, was drawn on fences, walls, houses, roads, in the snow and otherwise in the public sphere. It was also used in illegal art. Coins with the H7 symbol were also attached to clothes. Such coins were confiscated by the Nazi authorities. It was also used in the private sphere, among others on the inside of blinds.
