Plastic Wheel Well Liner
This automotive maintenance tutorial was specifically written to assist owners of the "new" Type 312 (2008, 2009, 2010, 2011, 2012, 2013, 2014 and 2015) Fiat 500 hatchback supermini car in changing a burnt out front turn signal or DRL (daytime running light) bulb located in the front bumper cover below the headlight housing.

Owners of other Fiat, Alfa Romeo, Chrysler, Dodge, Jeep and RAM vehicles such as the 4C, Giulia, 200, 300, Town & Country, Challenger, Charger, Dart, Durango, Journey, Grand Caravan, Compass, Grand Cherokee, Wrangler, Renegade, Cherokee, Patriot, 1500, C/V Tradesman and ProMaster may also find these DIY instructions to be helpful.

Replacement bulbs with their part numbers are as follows: Front Turn Signal # WY21W (also 7440A or 7440NA) and DRL # W21/5W or 7443.

No tools are needed to change either light bulb.

Pull Open Access Cover
Access Panel Removed
Round Plastic Dust Cover
The first step is to turn the steering all the way in the opposite direction of the burnt out turn signal or DRL light bulb.

Turning the front wheels will give you more working room in the wheel well to access the bulb sockets.

Gently pull back the release tab on the rectangular access panel before pulling it out of the black plastic wheel well liner or "splash guard".

Set the access cover aside in a safe place.

Set the dust cap aside in a safe place.
