Differences between T10 and T20 lamps that you need to know

T10 and T20 lamps are two types of lamps that are used in various applications, especially in the automotive industry. Here is a brief introduction to both:

1. T10 lamps:

   • T10 lamps are also known as “W5W” in the European automotive lamp numbering system.
   • This is a type of small incandescent lamp that is often used as parking lights, license plate lights, or interior lights in vehicles.
   • T10 lamps have a cylindrical body shape with a T10 base socket which refers to the diameter base, which is about 10 mm.
   • They are usually available in a variety of types, including conventional incandescent lamps, LEDs, and xenon lamps (HID).
   • The most commonly used T10 lamps are conventional incandescent with wedge socket (tungsten filament) or LED lamps with better efficiency and longer life.

2. T20 lamps:

   • T20 lamps are also known as “7440” or “7443” in American automotive lamp numbering.
   • These are a larger type of lamp compared to T10 lamps and are usually used as brake lights, taillights, or signal lights in vehicles.
   • T20 lamps also have a T20 base socket, which refers to the diameter of the base, about 20 mm.
   • Like T10 lamps, T20 lamps are also available in various types , including conventional incandescent lamps, LEDs and xenon lamps.
   • The T20 lamps that are often used are brake lamps with a 7443 socket which can function as a brake lamp and signal lamp in one unit.
