Buy Ford Maverick Parking, Corner, Side Marker, Signal Light

Overview

The Ford Maverick's turn signal light-also called an indicator lamp, blinker, or directional signal-lets other drivers know which way you plan to go. On every Maverick, the front signals sit inside the head-lamp housing, while the rear lamps share space with the tail/brake cluster. Recent models (2022-2025) use a 4257NA dual-filament bulb up front and 7440 bulbs in back, both controlled by the Body Control Module (BCM). Knowing the bulb type, fuse location, and recall info helps you keep the signals bright, legal, and safe.

Basic Job

Turn signal lights flash bright amber (or red at the rear on some markets) to tell others you are turning, changing lanes, or merging. The BCM keeps the flash rate near 90 blinks per minute; if it rises, that's a hint a bulb is burned out (Maverick Truck Club). Good signals cut crash risk by making your path clear to everyone (IIHS-HLDI).

Bulb & Socket

• Front (2022-25 truck) - 4257NA/HP24 dual-filament halogen; fits twist-lock socket inside head-lamp (Ford Service Content).
• Rear (2022-25) - twin 7440 bulbs each side, controlled by BCM (Motor Safety).
• Classic 1970-77 car - separate round 1157 (front) and 1156 (rear) in chrome bezels (mmb.maverick.to).

Compatibility

Any bulb or LED marked SAE J588 meets fit and brightness rules for vehicles under 2 m wide (Society of Automotive Engineers). When upgrading to LEDs, choose units with built-in resistors or add 6-ohm load resistors so the BCM does not "hyper-flash" (Maverick Truck Club).

Common Problems

• Single-sided fast flash - burned-out bulb or broken filament.
• Both sides fast flash - BCM sees low resistance after LED swap.
• No flash/no click - blown 15-A fuse F24 or faulty BCM logic (Maverick Truck Club, Maverick Truck Club).
• Moisture in lens - cracked seal lets water corrode contacts (Maverick Truck Club).

DIY Diagnosis

1. Walk-around test with hazards on.
2. Swap bulbs left⇄right; if problem moves, bulb is bad.
3. Meter the socket for 12 V with key on and stalk up.
4. Check fuse in under-hood box-diagram molded into lid (Maverick Truck Club).
5. Scan codes; BCM sets B1D50 (front) or B1D52 (rear) for open circuit (Motor Safety).

Replacement Steps

1. Turn wheel outward for room.
2. Unclip head-lamp cover.
3. Twist socket counter-clockwise and pull out (Ford Service Content).
4. Press bulb tab, install new bulb without touching glass.
5. Reverse steps and test. Total time: 10 minutes per side.

Tools Needed

Flat trim tool, T-20 Torx driver, nitrile gloves, multimeter, dielectric grease. No relay puller needed-Maverick uses solid-state BCM instead of a flasher can (Maverick Truck Club).

Maintenance Tips

• Clean lenses with mild soap; avoid harsh solvents.
• Grease socket seals to block water.
• Replace bulbs in pairs for even brightness.
• Check flash rate during every oil change.

Legal Rules

U.S. code FMVSS 108 sets color (amber front, amber or red rear), brightness, and flash rate (eCFR). State traffic manuals (MUTCD) add rules for trailer turn lamps and converter dollies (FMCSA, MUTCD). Using LEDs is legal if they stay amber and meet SAE dots. After a recall (23C41) Ford now alerts drivers only if both rear bulbs fail; dealers flash the BCM to fix this (Ford Motor Company, AP News).

Safety Impact

IIHS crash data shows drivers with fully working blinkers are hit less often in side impacts (IIHS-HLDI). Bright turn lamps also help pedestrians predict your moves, giving them more time to react (, IIHS-HLDI).

Upgrades & Mods

Owners install switchback LEDs that glow white as running lights and flip to amber when signaling; choose ones that match 4257 socket and include a CAN-bus resistor (Lasfit®, Diode Dynamics). Side-marker kits that tie into the turn circuit add extra visibility in fog (Maverick Truck Club).

Cost & Lifespan

• Halogen 4257 bulb ≈ $3, 1-year average life.
• Quality LED ≈ $40, 10+ years.
• DIY swap costs almost nothing but time; shop labor averages $25-$50.
  Bright LEDs cut long-term cost because they use less power and rarely burn out (Sylvania Automotive).

Green Disposal

Old bulbs contain glass and metal-recycle them at community haz-mat days. Never toss into trash; shards can hurt wildlife and people (MUTCD).

Frequently Asked Questions

Q: What bulb fits the front of a 2022-25 Maverick?
A: Use a 4257NA dual-filament or an LED marked "4257" and "SAE" (Ford Service Content, Lasfit®).

Q: Why does my blinker flash fast?
A: The BCM senses low resistance-usually a burned bulb or an LED without a resistor (Maverick Truck Club, Maverick Truck Club).

Q: Can I swap only one bulb?
A: Replace both on the same end so brightness stays even and lenses match (Ford Service Content).

Q: Are LED turn signals legal on a Maverick?
A: Yes, if they stay amber, fit the 4257 socket, and meet SAE J588 (Society of Automotive Engineers).

Q: Where is the turn-signal fuse?
A: Under the hood, fuse F24 (15 A) supplies both front blinkers (Maverick Truck Club).

Q: Does the Maverick use a flasher relay?
A: No. The Body Control Module handles timing, so you won't find a separate relay to swap (Maverick Truck Club).

Q: What is hyper-flashing?
A: A very fast blink that warns of low circuit resistance; common when an LED replaces a halogen without a resistor (Maverick Truck Club).

Q: How do I clear moisture in the lens?
A: Remove the bulb, dry the housing with gentle heat, and reseal with fresh rubber gasket (Maverick Truck Club).

Q: Do recalls cover turn signals?
A: Yes. Recall 23C41 adjusts the BCM so it warns if even one rear bulb fails (Ford Motor Company, New York Post).

Q: Why does my trailer light not blink?
A: Check the four-flat connector ground and trailer fuse in the bed junction box (Maverick Truck Club).

Q: Are amber rear signals safer than red?
A: NHTSA studies show amber cuts rear-end crashes, but U.S. rules still allow red (Wikipedia).

Q: Can rain short-out the circuit?
A: Yes; water lowers resistance and may blow the fuse. Keep seals tight and use dielectric grease (Maverick Truck Club).

Q: What tools do I need for a bulb swap?
A: Torx driver, flat trim tool, gloves, and new bulb. No scanner needed for simple change (Ford Service Content).

Q: How long do LEDs last?
A: Quality LEDs can glow for over 30,000 hours-many years of normal driving (Lasfit®).

Q: Will the dash warn me if a front bulb burns?
A: Yes; the BCM triggers a fast flash and message center alert (Maverick Truck Club).

Q: Does upgrading to LEDs void warranty?
A: No, but damage caused by the part (such as melting housing) is not covered (Motor Safety).

Q: Can I mix LED front and halogen rear bulbs?
A: Yes, but use resistors so flash rate stays normal (Maverick Truck Club).

Q: Where can I find wiring diagrams?
A: The Ford service manual PDFs list every wire color and pin location (Ford Service Content).

Q: How do I recycle old bulbs?
A: Drop them at local household hazardous-waste events or auto-parts recycling centers (MUTCD).

Q: Does BCM software affect signal timing?
A: Yes. Updates can change flash logic and error detection (Reddit).
