2017 Ford Mustang Headlight Bulb Size
Ford refined the S550 for 2017 with heritage colors like Grabber Blue, the optional MagneRide damping system, and a new 10-speed automatic on the GT — turning the Mustang into a legitimate grand tourer without losing its muscle car soul. The 2017 Ford Mustang headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. The V6 and base EcoBoost come equipped with halogen headlights, while the GT and Premium trims feature factory LED units.
For 2017 Mustang owners still running halogen low beams, the upgrade to 2017 Ford Mustang LED headlights is one of the best dollar-for-dollar modifications on the car. The difference is immediately visible — sharper cutoff lines, whiter light, and a front-end presence that finally matches the heritage paint and aggressive body lines Ford gave this model year.
Best Headlight Upgrade Options for the 2017 Mustang
The 2017 Mustang sits at the sweet spot of the pre-facelift S550 generation — all the refinements of three years of production with none of the parts-availability concerns that later models occasionally face. LED headlight kits for the H11 low beams deliver a daylight-white beam that activates at full intensity the instant you switch them on. There is no warm-up delay and no color shift over time, which matters on a car you might be cruising in for hours on a grand touring run.
HID conversion kits offer an alternative path for owners who prioritize maximum throw distance. The xenon arc pushes light farther down the road than LED at equivalent wattage, making HIDs particularly effective on dark, winding backroads where early visibility is critical. A compact ballast installs behind each headlight housing, and the total job usually takes under an hour.

Frequently Asked Questions
What are the headlight bulb sizes on a 2017 Ford Mustang?
The 2017 Ford Mustang takes H11 bulbs for the low beams, 9005 bulbs for the high beams, and H11 bulbs for the fog lights. This fitment applies to the V6, EcoBoost, GT, and GT350. Trims with factory LED headlights use integrated LED modules that are not bulb-replaceable in the same way, but halogen-equipped trims accept direct plug-and-play LED or HID conversion kits.
Does the 2017 Mustang with MagneRide have different headlights?
No. The MagneRide suspension option on the 2017 Mustang affects the dampers only and has no connection to the headlight system. Whether your 2017 Mustang has the standard suspension or the MagneRide package, the headlight bulb sizes remain H11 low beam and 9005 high beam. LED and HID conversion kits install identically regardless of your suspension setup.
Can I upgrade the fog lights and headlights together on my 2017 Mustang?
Absolutely, and we recommend it. The 2017 Mustang uses H11 bulbs in both the low beam and fog light positions, which means one LED kit in the H11 size covers both. Matching all forward-facing lights to the same 6000K white ensures a cohesive look and eliminates the yellow-white mismatch that occurs when only the headlights are upgraded. Many owners order two sets of H11 LEDs to handle headlights and fogs simultaneously.
Will the 10-speed automatic affect LED headlight installation?
Not at all. The 10-speed automatic transmission introduced on the 2017 Mustang GT has no bearing on headlight fitment, wiring, or installation. The headlight circuit is independent of the drivetrain electronics. Whether you have the 6-speed manual, the 6-speed auto on the EcoBoost, or the new 10-speed on the GT, the LED or HID swap is the same straightforward plug-and-play process.
How do LED headlights hold up on long highway cruises in the 2017 Mustang?
LED headlights are ideal for the kind of long-distance grand touring the 2017 Mustang was built for. Unlike halogen bulbs, which dim gradually over their lifespan, LED bulbs maintain consistent output for tens of thousands of hours. They draw less power from the electrical system, generate minimal heat, and the 6000K color temperature reduces eye fatigue on extended nighttime drives — making them the preferred choice for Mustang owners who actually use their cars.
