Bayonet-Base Miniature Light Bulbs


Double Contact, Tubular Bulb	Double Contact, Globe Bulb	Double Contact, Tapered Bulb	Small Bayonet Base

Pins on either side of the base lock these bulbs into sockets. These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

LED—LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.

Incandescent—Incandescent bulbs are traditional light bulbs.

Plastic Bulb—Plastic-coated glass and plastic bulbs are more shatter-resistant than glass.
