Sockets & Lamp Holders

A light socket or lamp holder is simply an electrical connector used for installing electric lights. The four major types of lamp holders are:

• Edison Screw
• Bi-Pin Base (Plug-in Style)
• Bayonet Mount/Twist Lock
• Wedge Base

The Edison Screw connector is typical in flashlights to streetlights. The Bi-Pin type (plug-in style) has pins in one or both ends and is typically used in halogen lights and fluorescent tubes. A Bayonet Mount is an older technology used in automotive lighting, and the Wedge Base type of connector is used with Christmas lights and newer automotive lamps. Other than the major types, there are a few unusual types of connectors, so if you can’t find the socket or lamp holder you need, please contact one of our lighting experts at 1-800-458-8369.
