Why so many numbers?
The H4 designation was assigned to the first Halogen dual filament bulb homologated by the ECE (European Union) in 1970. It is the most common bulb in use world wide. It has many variations in voltage, wattage, color and construction.The single over-riding criteria is that it will fit in a lamp designed to the H4 standard.
In 1983 Ford Motor Company applied to USDOT for a replaceable bulb lamp design to allow the use of aerodynamic headlamps. They designated use of an H4 bulb but with changes and the DOT designation 9003 was assigned. These changes involved voltage, Wattage and light color while maintaining the basic H4 design. There were some other changes made primarily in the area of construction tolerances. A 9003 is basically an H4 12 volt 60/55 watt bulb with a light color of about 3200ºK. Since 9003 and H4 are not the same, ECE applied a new designation of HB2 to the 9003 for cars exported to the US market.
Even though the 9003/HB2 and H4 are simular and physically interchangeable, only the 9003 bulbs are legal for street use in the USA.
