We are a team of ASE certified mechanics that have created this guide to help
you save money while doing the job yourself, or at least see what you are paying
for when having the job done at a shop. A turn signal bulb is part of the directional
lighting system and can be incorporated into the brake light system on some models.
What Goes Wrong?
As with any non LED light bulb after time and usage the filament becomes fatigued
and will break causing the bulb to not light up, this is easily fixed by replacing
What's the Cost?
A small replacement light bulb such as brake or turn signal bulb will cost from
$7.00 to $14.00 and about .3 to .8 hours of labor in most cases, this repair many
people can do themselves while using simple tools. If exact times or procedures
are needed you can ask our experts to supply you with
the information (free), or consult an online resource such as AllData DIY (pay),
this guide and video will be sufficient in most cases. When replacing automotive
bulbs use quality replacements to avoid premature failure.
Lets Jump In!
There are two different styles of bulb maintenance procedures, the first
style requires the removal of the lens to access the bulbs while some manufacturers
supply an access door which is the example we are using in this guide, additional
configurations are featured in the videos below. First, identify the turn signal
light (blinker) that has failed, inspect both front and rear bulbs to ensure
the turn signal system
is not the problem.
There will be an access door behind the lens to replace the bulb, if not
you will need to remove the lens. Open the access door and the rear of the lens
will be exposed, there might be small screws or a plastic twist fastener that
may need to be undone.
Release the wiring connector from the bulb housing, some vehicles are designed
with bulb socket attached, in this case turn the socket counterclockwise to
Grasp and turn the release fastener to pull the bulb housing plate from
the lens, gently remove the bulb mounting plate which will expose the various
bulbs including the turn signal, this configuration can be different depending
Identify the failed blinker bulb, this failure is sometimes accompanied
by a darkish color inside the bulb glass. While holding the plate down, gently
grasp the failed bulb and twist counterclockwise while pushing down slightly,
then pull up to remove, some bulbs just pull straight out.
Watch the Video!
Please watch this video of the job being done, then continue down the guide
to glean additional helpful information.
Once the bulb has been removed, inspect the bulb and socket for corrosion
or damage, occasionally a bulb electrical contact can become overheated and
burnt due a to high resistance of a poor connection, this will hinder the new
bulb operation. Use a sharp object such as an Exacto blade or sandpaper to clean
the contact by scraping the terminal exposing new metal.
Match the new bulb to the old unit, they should match identically,
do not install incorrect bulbs this can cause lighting system electrical issues.
It's important that the bulb terminals are the same, some bulbs are designed
with two terminals which can cause operational problems if installed.
Gently install the new bulb by inserting (push down) and twisting it clockwise
(or push straight in), It's also a good idea to include dielectric grease as
well when installing the bulb to protect the connections.
Reconnect the wiring harness connector to the blinker bulb mounting plate.
Turn the ignition switch on while engaging the blinker lever to operate
the turn signal bulb ensuring the repair is done correctly and reassemble.
