Quick take:
A turn-signal light-also called a blinker, indicator, or direction lamp-lets drivers show where they plan to go. On every GMC Yukon, working flashers are required for safety, law, and daily driving.

Overview

The Yukon's front lamps flash amber and the rear lamps flash red or amber. They warn other road users and help you pass yearly inspections. Federal rules say both sides must be visible within a 45-degree sweep at 3 m (10 ft) away (NHTSA), and trucks/SUVs under 80 in. wide must carry one blinker per corner (eCFR).

Fit & Years

Yukon generation	Typical front/rear bulb*	Notes
2000-2014	3157/3156	Dual-filament halogen, easy swap
2015-2020	7443/7440	Single-filament, fits HID headlights (ManualsLib)
2021-2024	LED board	Service as a module, not a bulb

*Always match your VIN or owner's manual before ordering. The 2015 XL manual shows the turn-signal socket in the headlamp housing and lists replacement bulbs on page 10-33 .

Safety & Law

Color: Amber up front; amber or red in back (eCFR).
Height: 15-83 in. above the road .
Visibility: Must meet SAE J588/J578 color and angle rules (sae.org).
Failure signals: A burned-out lamp makes the dash arrow blink fast (hyper-flash) to warn the driver, a feature GM has used for years (NHTSA Static).
Driver behavior: Studies show reminder chimes and lane-change alerts boost teen turn-signal use (IIHS Crash Testing).

Bulb Choices

Type	Brightness	Life	Pros	Cons
Halogen	16-24 lm/W	≈3,600 h	Cheap, OE look	Runs hot (blog.recessedlighting.com)
LED retrofit	80-100 lm/W	25,000 h+	Crisp light, low power	Needs resistor or smart flasher to avoid hyper-flash (Motor Vehicle Maintenance Stack Exchange)
Factory LED module	6,000 lm per pair typical (The Times)	30,000 h	Bright, sealed	Costly assembly

Very bright LEDs can dazzle oncoming traffic if the reflector is not designed for them ().

Common Problems

Fast flash / hyper-flash - Low resistance when one bulb burns out or when LEDs replace halogens (Motor Vehicle Maintenance Stack Exchange).
No flash at stalk - Loose stalk bracket; GM issued a service bulletin to replace the whole lever/bracket (NHTSA Static).
Lights stay on after exit - 2021-2022 BCM software; dealer reflash fixes battery drain (NHTSA Static).
No audible tick - Radio module glitch silences relay sound (NHTSA Static).
Blown fuse - Check "Right/Left Trailer Stop-Turn" fuses in the instrument-panel block (2012 diagram) (startmycar.com).

DIY Replacement

Tools: flat screwdriver, 7 mm socket, gloves.
Steps (2015-2020 shown):

Remove headlamp trim screws and pull lamp forward.
Turn socket counter-clockwise, pull out (ManualsLib).
Release clip, swap bulb, avoid touching glass.
Test flash; if you installed LEDs, add load resistors or a CAN-bus flasher to stop hyper-flash (Motor Vehicle Maintenance Stack Exchange).
Refit lamp and screws. Total time: ~15 min.

Care Tips

Clean lenses with mild soap; cloudy plastic cuts brightness.
Use dielectric grease on socket seals.
Inspect wiring yearly; vibration can loosen Yukon front housings (NHTSA Static).
Replace bulbs in pairs so left and right match in color and intensity.

Upgrade Ideas

Switchback LED: Shines white as a parking lamp, switches to amber when blinking-legal up front if amber during flash (eCFR).
Sequential modules: Add eye-catching flow patterns (check state law first).
Smoked lens covers: Style upgrade; be sure they don't cut output below SAE minimums (sae.org).
Smart flasher relay: Cures hyper-flash without resistors and restores normal tick sound.

Cost & Time

Halogen bulb: US $5-10.
Quality LED retrofit: US $30-50 per pair.
Factory LED module (2021-24): US $120-250 per side.
Labor at a general shop takes about 0.3 hr; many owners DIY in the driveway.

Frequently Asked Questions

Q: Why is my Yukon blinker blinking twice as fast?
A: One side's bulb has burned out or you installed low-draw LEDs without a resistor or updated flasher (Motor Vehicle Maintenance Stack Exchange).

Q: What color should the front turn signal be?
A: Amber only, per federal rules (eCFR).

Q: Can I use red LEDs in the back?
A: Yes-rear signals may be amber or red on U.S. vehicles .

Q: Do brighter lights make driving safer?
A: Up to a point; very high-output LEDs can glare and cause complaints (The Times).

Q: What bulb size does a 2013 Yukon use?
A: Most 2008-2014 trucks take 3157 dual-filament bulbs front and rear. Check your exact trim to be sure.

Q: How long do factory LEDs last?
A: Lab estimates are 30,000 hours-about the life of the vehicle .

Q: Where is the turn-signal fuse?
A: Look in the instrument-panel fuse block, cavities F1 (Left) and F3 (Right) on 2012 Denali / similar years (startmycar.com).

Q: My stalk feels loose; any fix?
A: GM bulletin N212355910 calls for replacing the stalk and bracket when the snaps won't stay engaged (NHTSA Static).

Q: Will LEDs void my warranty?
A: Bulb changes generally don't, but wiring damage from incorrect resistors might. Save your old parts while under warranty.

Q: Can dull lenses fail inspection?
A: Yes-if output falls below the visibility requirement stated by SAE J588 (sae.org).

Q: Are Yukon turn signals part of daytime running lights (DRL)?
A: On 2015-2020 models, the same 7443 LED acts as DRL at full power and blinker at flasher power.

Q: Do I need special tools?
A: No, just hand tools and gloves for most years.

Q: What causes silent blinkers?
A: Certain radio software versions mute the click; dealers re-flash the module (NHTSA Static).

Q: Can a dead battery be linked to turn signals?
A: Yes-2022 software could leave them on after the key was removed; BCM update fixes it (NHTSA Static).

Q: How often should I check them?
A: At every fuel stop-burned-out bulbs invite tickets and crashes.

Q: Does using the hazard switch override bad bulbs?
A: No; if a bulb is out, hazards on that side will not flash.
