Buy Pontiac Firebird Turn Signal Light Sockets

The Pontiac Firebird turn signal light socket-also called the indicator lamp holder or blinker bulb connector-grips the bulb and feeds it 12‑volt power so the signal flashes whenever you move the stalk. (HowStuffWorks)
It is part of the car's lighting system, which uses replaceable incandescent or LED bulbs held in sockets just like this one. (Wikipedia)
Every Firebird, from the first 1967 model to the last 2002 coupe, uses front and rear sockets; in 1975 the factory even raised the front openings into the grille for better visibility. (Wikipedia)
Federal law sets brightness, color, and durability rules for these lamps in the U.S. FMVSS 108.

The socket locks the bulb with twist‑lock tabs or push‑in wedges so bumps and vibration cannot loosen the connection. (Family Handyman)
It also carries a ground wire and one‑ or two‑lead power feed, making it the quick‑disconnect point when you change a lamp housing, as shown in this simple repair guide.

On most Firebirds the front socket hides behind the parking‑lamp lens just below the headlamp, while the rear socket plugs into the tail‑lamp panel under the hatch trim. (Wikipedia)
Removing two screws lets you slide the lamp outward, twist the connector a quarter‑turn, and pull it free. (Instructables)

Early Firebirds use metal‑base bayonet bulbs, while later models switch to plastic wedge bulbs that need less twist force. (Wikipedia)
The 1975 facelift moved the sockets up into the grille, an easy visual cue between 1974 and 1975 cars. (Wikipedia)
Fourth‑generation cars added three‑wire "park/turn" sockets so one dual‑filament bulb can glow dim for parking lights yet flash bright for signaling. (HowStuffWorks)

Corrosion on the contacts is the #1 killer, often showing up as white or green powder that blocks current. (TDIClub Forums)
Heat from a high‑watt bulb can char the plastic and loosen the spring clip, making the bulb wiggle or fall out. (Family Handyman)
When the circuit opens, the flasher sees low load and makes the dash arrow blink twice as fast. (Reddit)

Fast "hyper‑flash" on the dash or a rapid clicking relay tells you the socket or bulb is bad.
A lamp that works if you tap the lens but quits on bumps hints at loose tabs in the holder. (Family Handyman)
Discolored plastic, a burnt smell, or green spots inside the cavity all point to corrosion. (TDIClub Forums)

Set a multimeter to continuity; touch one probe to the socket ground and the other to the bulb shell-if it beeps, the ground is good. (YouTube)
Switch to DC volts, probe the power pin, and you should see about 12 V when the stalk is on. (Reddit)
Voltage but no light means the holder spring is weak or the contacts are dirty. (Family Handyman)

Twist the old blinker socket counter‑clockwise and pull it straight out of the lamp. (Instructables)
Strip and crimp the new pigtail wires with heat‑shrink butt connectors for a weather‑tight seal. (Family Handyman)
Before you seat the bulb, wipe a tiny dab of dielectric grease on the contacts to keep out water. (Bob Is The Oil Guy)

Swapping to an LED bulb cuts power draw but can trigger hyper‑flash because the flasher thinks a bulb is burned out. (Instructables)
Adding a 6‑ohm, 50‑watt load resistor in parallel with the lamp-or installing an electronic LED flasher-restores normal blink speed.
Because LEDs run cooler, sockets usually last longer and resist melting. (Wikipedia)

Re‑grease the contacts each time you replace a bulb; the thin silicone barrier keeps water and salt out. (Sawmill Creek Woodworking Community)
Use only a light film-too much grease can insulate the contacts and stop current flow. (vfrdiscussion.com)

United States FMVSS 108 says front signals must shine amber and rear signals red or amber and be visible 500 feet in normal sunlight.
The rule was reorganized in 2007 for clarity, but performance requirements such as brightness and location did not change. (Federal Register)

Q: What does the turn‑signal socket do?
A: It holds the bulb and carries power and ground so the signal can flash. (HowStuffWorks)

Q: Where is it on my Firebird?
A: It twists into the parking‑lamp housing up front and into the tail‑lamp panel at the rear. (Instructables)

Q: How can I tell it is bad?
A: Rapid dash flashing or a dark bulb that tests good usually means the socket is corroded or loose. (Reddit)

Q: Can I clean a rusty socket?
A: Yes-disconnect the battery, spray electrical contact cleaner, scrape gently, and add dielectric grease before re‑installing. (TDIClub Forums)

Q: What grease should I use?
A: Apply silicone dielectric grease; it seals out moisture without conducting electricity. (Bob Is The Oil Guy)

Q: Will an LED bulb work?
A: Yes, but you'll need a load resistor or LED‑friendly flasher to stop hyper‑flash. (Instructables)

Q: Do I have to solder the new socket?
A: No; most come with pigtail wires-crimp or heat‑shrink butt connectors make a strong, weather‑tight joint. (Family Handyman)

Q: Should I disconnect the battery first?
A: Yes-pulling the negative cable prevents shorts while you handle the wiring.

Q: Why does grease need to be thin?
A: A thick blob can insulate the contacts and stop current flow; less is more. (vfrdiscussion.com)

Q: Is there a federal recall on Firebird turn‑signal sockets?
A: No recalls exist, but the sockets must meet FMVSS 108 brightness rules to pass inspections. (eCFR)
