Buy Dodge Challenger Parking, Corner, Side Marker, Signal Light

Overview

The Dodge Challenger's turn-signal light-also called a *blinker*, *indicator lamp*, or *directional light*-tells other drivers when you plan to turn or change lanes. Keeping this light working matters for safety, legal compliance, and even style.

How It Works

A turn-signal circuit uses a switch in the steering column, a flasher module (or BCM logic in newer cars), wiring, and the front- and rear-mounted lamps. When you move the stalk up or down, the circuit closes and the bulbs blink at about 60-120 flashes per minute ([HowStuffWorks]). 2008-2014 Challengers use a thermal flasher and amber 3457-series bulbs, while 2015-present models house LED boards inside the headlamp assembly ([Mopar Vehicle Information], [Mopar Vehicle Information]).

---

Legal Basics

U.S. rule **FMVSS 108** says front indicators must be amber and rears may be amber or red, mounted 15-83 inches high and as far apart as practical ([eCFR], [eCFR]). Using the wrong color lens-or deleting the signal entirely-can fail inspection. You can read the full text in the federal register at [FMVSS 108](https://www.ecfr.gov/current/title-49/subtitle-B/chapter-V/part-571/subpart-B/section-571.108).

Safety Facts

* LEDs light up about 0.2 seconds faster than filament bulbs, giving the driver behind you up to 18 feet more stopping distance at 60 mph ([SAE International], [Consumer Reports]).

* Interior "fast-flash" is an intentional warning that an exterior bulb is out; if both inside and outside blink quickly, replace the bulb or socket ([NHTSA], [NHTSA]).

* Roughly one in four U.S. drivers skips signaling a turn, and nearly half forget to signal lane changes ([HowStuffWorks])-a reminder that a working lamp alone is not enough; you must use it.

---

Common Problems

* **Burned-out bulb** - most frequent on 2008-2014 cars; causes rapid flashing.

* **LED board failure** - on 2015+ models, the whole headlamp may need replacing because the LED driver is sealed inside ([Challenger Talk]).

* **Socket corrosion or loose terminals** - leads to intermittent blinking ([NHTSA]).

* **Moisture inside lens** - fogs the housing and shorts contacts.

---

Maintenance Tips

1. Check the blinkers during every fuel stop-walk around and watch reflections off nearby surfaces.

2. Keep the clear outer lens clean with mild soap; dirt dims light output.

3. Apply dielectric grease to bulb bases on pre-LED models to fight corrosion.

Replacement Guide (DIY)

*Tools:* T-25 Torx, 8 mm socket, trim-panel remover, gloves.

1. Turn the wheel inward and remove 3-4 plastic fender-liner clips.

2. Reach behind the bumper and twist the bulb socket ¼-turn counter-clockwise.

3. Swap the **3457NA** (front) or **3157K** (rear) amber bulb; do not touch the glass.

4. Test before reinstalling the liner.

Cost & Time

A do-it-yourself bulb costs ≈ \$5-\$25 and 20 minutes. A shop will charge about \$40-\$60 labor. If the **combination switch** fails, average repair runs **\$213-\$273** including parts and labor ([RepairPal.com]).

---

Upgrades & Mods

* **Switchback LEDs** - shine white as running lights and switch to amber when signaling.

* **Sequential kits** - create a side-to-center sweep pattern (allowed if timing still meets FMVSS rates).

* **Smoked lenses** - reduce glare but must still emit the legal color.

* **Blind-spot systems** - some aftermarket mirrors flash an extra LED when the blinker is on and a car sits in your blind spot ([HowStuffWorks]).

Troubleshooting Chart

| Symptom | Likely Cause | Quick Fix |

| ---------------------- | ----------------------------- | ------------------------------------- |

| Fast flash on one side | Burned bulb | Replace bulb |

| No flash, solid light | Flasher relay stuck | Replace relay or BCM flash |

| Both sides out | Blown fuse | Check fuse F11 in IPM |

| Works but very dim | Dirty lens or wrong bulb type | Clean lens; install proper 3457NA/LED |

Frequently Asked Questions

Q: What bulb type fits a 2014 Challenger front signal?

A: Use an amber **3457NA** or compatible LED of equal brightness. ([Mopar Vehicle Information])

Q: Do 2015-plus models use bulbs?

A: No. They use built-in LED boards housed in the headlamp; if one LED fails, the entire assembly is replaced. ([Challenger Talk])

Q: Why is my dash arrow blinking fast?

A: Fast flash warns that an exterior bulb on that side is burned out or has a wiring fault. ([NHTSA])

Q: Can I install red rear blinkers?

A: Yes-federal rules allow amber **or red** rear turn signals, but front ones must stay amber. ([eCFR])

Q: Are smoked lenses legal?

A: Only if they still let enough amber/red light through to meet brightness standards in FMVSS 108. ([eCFR])

Q: How often should I check my blinkers?

A: At least once a month or before any long trip for early fault detection. ([Mopar Vehicle Information])

Q: Does LED really improve safety?

A: Yes-LEDs light up about 0.2 s faster, giving followers more reaction time. ([SAE International], [Consumer Reports])

Q: My socket looks burnt. What now?

A: Replace the socket or pigtail; loose pins cause heat that melts plastic ([NHTSA]).

Q: Can bad tinting kill the signals?

A: Yes-water from windshield-tint jobs has corroded Challenger BCMs, disabling lights. ([NHTSA])

Q: Are sequential signals legal?

A: Yes if the full cycle stays between 0.5 - 1.5 seconds as required by FMVSS 108. ([eCFR])

Q: What happens if I don't signal?

A: Studies show drivers fail to signal 25 % of turns and nearly half of lane changes, increasing crash risk. ([HowStuffWorks])

Q: Where can I read the owner's manual?

A: Download a free PDF at [Dodge's site](https://vehicleinfo.mopar.com/assets/publications/en-us/Dodge/2020/Challenger/P136135_20_LA_OM_EN_USC_DIGITAL.pdf). ([Mopar Vehicle Information])
