I need a part/oem number for a turn signal light bulb socket

To access the front driver's side turning light of a 2008 Lincoln MKZ, you will need to follow these steps:

1. Open the hood of the car and locate the headlight assembly on the driver's side.
2. Look for the turn signal bulb socket, which will be located at the bottom of the headlight assembly.
3. Turn the bulb socket counterclockwise to release it from the headlight assembly.
4. Gently pull the bulb and socket out of the headlight assembly.
5. Pull the old bulb out of the socket and discard it.
6. Insert a new turn signal bulb into the socket, making sure it is securely seated.
7. Reinsert the bulb and socket into the headlight assembly and turn it clockwise to lock it in place.
8. Test the turn signal to ensure it is working properly.
9. Repeat these steps for the front passenger side turning light if needed.

It's important to note that the exact process may vary slightly depending on the specific model year of your MKZ, so you may want to consult your owner's manual for more detailed instructions or diagrams.

Use a 12v test light to make sure you are getting power to the bulb socket. If so, you can say it's a bad socket. If not, you need to get power to the bulb to expect it to light.

Dear Alex,
The problem is in the bulb, or the socket, or the wiring to these.
Whenever a turn signal flashes fast, know that one of the bulbs is not working.
You have already identified the problem as being the front one. Problem could be the hot wire, or the ground wire, or the ground connection to this bulb.
Start by taking a tester to the hot wire, and see if it is receiving electrical impulses when the turn signal is on.
( It probably is, unless the car has been in a wreck and has been improperly repaired.)
Then check the socket or the wires to is and see if the bulb is grounded.
I suspect the ground is defective, and either a new socket or a repair to the ground wire should fix you rights up.
God bless your efforts.

If bulb or socket melted then replace socket. May be OEM part not sure. Easy fix just be sure to use seal type crimp connectors or you will be working on this a year later.

The tail light circuit is separate from the brake and turn signal circuit. Either the bulb socket has gone bad or a wire has flaked out. Check for voltage at the socket on either pin base when you have your parking lights on. If voltage is present, it is either a worn socket failing to hold the bulb properly, or another bad bulb. If no voltage, determine which wire on the other side is tail light power, and run a new wire across to the side that isn't working and connect it to provide power.

its is not uncommon for the contacts in the sockets to become corroded or just expand to the point of where they do not contact the bulb,try to test the socket with a multimeter for voltage,if it has voltage then its most likely the contacts,which sometimes can be rebent,but replaceing the sockets is a better solution,and can be picked up at most stores or 4x4 shops and junk yards.

This may have more then one bulb in the front or possibly a bad socket try wiggling the new bulb in the socket to see if it will work.Compare all turn signal lights that come on the passenger side to those drivers side.Some vehicles also incorporate sidemarker lights with the turn signals.

Front Turn Signal & Parking Lights



Remove the 2 parking light housing retaining screws ...



... then pull the housing away from the vehicle far enough to remove the bulb socket from behind the housing. Turn the socket counterclockwise and pull



Push the bulb in the socket gently and turn clockwise, then pull the bulb out of the socket. Note the offset retaining ears on each side of the bulb
