Bulb Types
This kit includes two bulb types, classied by their general shape.
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.

bayonet
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.
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 t the bulb socket like a
lament bulb, but are commonly polarity
sensitive.

General Tips
• When prying down on the assemblies to remove them, pry on the notched end of
the lens. Insert the narrow tool tip between the lens plastic and any metal collar
used to reinforce the lens mounting hole. Push in on the retaining clip rst to
compress and release it. Then pry down.
• The spring bulb retainer is also the circuit conductor. If necessary, gently bend
the metal retainer so it holds the bulb tight. This will help prevent intermittent or
ickering LED operation caused by a loose connection.
• Install the bulbs with the LEDs facing toward the lens.
