Bulb Types
This kit includes three bulb types, classified 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 filament.
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
filament tube.
WEDGE -
Wedge style bulbs get their name from the
shape of the bulb base. The tapered end of the bulb
“wedges” into the bulb socket.
LED wedge lights fit the bulb socket like a filament
bulb, but are polarity sensitive.
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 filaments to burn out. They emit a whiter light, run
cooler, and last longer that the incandescent (filament style bulbs) we are replacing in this
tutorial.
Unlike filament 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.
