Bulb Types

This kit includes two bulb types, classied by their general shape.

FESTOON - Conventional incandescent festoon bulbs have a shape and general

appearance that is similar to a glass fuse.

Metal caps attached to both ends of a

glass tube are sealed to the tube and

attached to the bulb lament. End caps

mount the bulb in its holder and also

conduct electrical current.

LED festoon lights have the same pointed

end caps, but are attached to a bank of

LEDs instead of a lament tube.

BAYONET - The bayonet base is formed

by a metal tube with radial pins on its

side that engage holes or tabs in the bulb

socket. A central electrical nub contact at

the tapered base of the bulb connects the

bulb to voltage.

While these are also polarity sensitive, the

socket design automatically orients the

bulb, ensuring correct polarity.

What are LEDs?

LEDs are Light Emitting Diodes, solid state devices that emit light when connected to electrical

current. They have no moving parts or wire laments to burn out. They emit a whiter light, run

cooler, and last longer that the incandescent (lament style bulbs) we are replacing in this

tutorial.

Unlike lament bulbs, LEDs are polarity sensitive. They have plus and minus (positive and

negative) electrical terminals that must match the polarity of the applied voltage. Installing the

bulbs “backwards” in the light bulb sockets (with reversed polarity) will not harm them, but they

will not light. Flipping the bulb 180 degrees in the electrical connector cures this problem.
