Our Verdict
The AlphaRex NOVA-Series full-LED projector headlight is the best overall upgrade for a 2015-2020 Mustang.
For 2015-2017 cars, the AlphaRex NOVA (around $1,250) delivers a full-LED projector beam, a sequential amber turn signal, and a switchback DRL in one plug-and-play housing. Running a 2018-2020 S550? Grab the year-correct AlphaRex NOVA (about $995). Want the look for less? The Raxiom GT350/GT500-style LED projector (around $685) is our value pick.
Shop Our Top Pick →Upgrading your 2015-2020 Mustang LED headlights is the single most transformative visual and functional mod you can make to an S550, and it takes about an hour with basic hand tools. Factory halogen and first-generation HID projectors on the sixth-gen Mustang throw a warm, yellow-tinted beam that looks dated next to a modern full-LED housing. At NLP Performance in Tampa, FL, the AlphaRex NOVA and Raxiom projector headlights are the two names our Mustang customers ask for by far the most — so below we compare five plug-and-play options for the 2015-2017 and 2018-2020 S550, with exact fitment, features, and pricing from about $557 to $1,250.
Why Upgrade the Headlights on a 2015-2020 Mustang?
Upgraded headlights are the highest-impact lighting mod for the sixth-generation (S550) Mustang because the factory units trade modern output for cost. Base 2015-2017 GT and EcoBoost cars shipped with halogen or first-generation HID projectors that produce a warm, roughly 3200K to 4300K beam, while a modern full-LED projector runs a crisp ~6000K with a tighter, better-defined cutoff. The result is more usable light down-road, faster sign recognition, and a face-lifted front end that finally matches the car's attitude.
There are three real reasons S550 owners swap headlights: visibility (a focused LED beam simply lights more road than a scattered halogen), styling (sequential amber signals and switchback DRLs bring the GT500 look to any trim), and reliability (sealed LED housings shrug off the moisture intrusion that clouds aging factory lenses). At NLP Performance we stock plug-and-play kits so you get all three without cutting a single wire.

2015-2017 vs 2018-2020: Get the Fitment Right
The most important thing to know before you buy: 2015-2017 and 2018-2020 Mustang headlights are not interchangeable. Ford gave the S550 a mid-cycle refresh for 2018 with a lower hood line and a reprofiled front fascia, so the headlight mounting and shape changed. Every reputable brand — AlphaRex and Raxiom included — sells a dedicated 2015-2017 housing and a separate 2018-2020 housing. Order the range that matches your model year and the swap is truly bolt-in.
Trim matters too. Many 2015-2017 GT, EcoBoost Premium, GT350 and GT500 cars left the factory with HID projectors, while some base cars used halogen reflectors. Full plug-and-play LED kits like the AlphaRex NOVA include the drivers and load management to run on either, but a handful of halogen-equipped cars benefit from a simple adapter to prevent turn-signal hyperflash. If you are unsure which you have, our Tampa team can confirm it by VIN before you order.

The 5 Best S550 Mustang Lighting Upgrades
1. AlphaRex NOVA LED (2015-2017) — Best Overall
The AlphaRex NOVA is the benchmark full-LED projector for the 2015-2017 Mustang. It bundles a genuine LED projector beam, a sequential amber turn signal, a switchback DRL, and AlphaRex's signature 'Activation Light' startup animation into one DOT/SAE plug-and-play housing. At around $1,250 it is the priciest option here, but it is also the only one that fully replaces the factory optics with LED and looks like a factory GT500 upgrade.
Key Specifications — AlphaRex NOVA (Top Pick)
What We Like
- + True full-LED projector with sharp ~6000K cutoff beam
- + Sequential turn signal + switchback DRL built in
- + Plug-and-play with startup 'Activation Light' animation
Things to Consider
- – Premium price at the top of the S550 range
- – 2015-2017 only — confirm your model year
2. AlphaRex NOVA LED (2018-2020) — Best for Refreshed Cars
Refreshed 2018-2020 Mustang? This is the same NOVA technology — full-LED projector, sequential signal, switchback DRL, Activation Light — in a housing shaped for the post-2018 front end. At about $995 it is a little cheaper than the 2015-2017 unit and remains our top pick for late S550 cars. Do not fit this to a 2015-2017 Mustang; use the year-correct kit above.
The 2018-2020 NOVA carries the same LED tech in a refresh-correct housing.
3. Raxiom GT350/GT500-Style LED Projector — Best Value
The Raxiom GT350/GT500 LED projector nails the aggressive C-shaped LED DRL look of the Shelby cars for roughly $685 — about half the price of the top-tier AlphaRex. It uses an LED daytime running light bar with a projector low beam and a blacked-out housing that pairs perfectly with a smoked front end. It is our value pick for 2015-2017 owners who want the Shelby face without Shelby money.
What We Like
- + Shelby GT350/GT500-style LED DRL for about half the AlphaRex price
- + Blacked-out housing suits smoked builds
- + DOT-compliant OE-style plug-and-play fit
Things to Consider
- – LED DRL rather than a full-LED projector beam
- – 2015-2017 fitment only
4. Raxiom OEM HID-Style Projector — Best Budget Refresh
If your factory lenses are yellowed or hazed and you simply want a clean, blacked-out OE look, the Raxiom OEM HID-style projector at about $557 is the most affordable way to do it. It is a straight OE-style projector replacement with a black housing and clear lens — no DRL bar drama, just a fresh, factory-correct headlight that reuses your HID or halogen bulbs. It is the budget entry point in this guide.
Raxiom's OE-style projector is the budget way to de-haze a tired S550 front end.
5. Raxiom Profile LED Tail Lights — Complete the Look
Great headlights deserve matching tails. The Raxiom Profile LED tail lights (about $543, and they fit 2015-2022 fastbacks) bring a full-LED signature and a sequential turn signal to the rear of the car, tying the front and rear lighting together. Adding them alongside any headlight above is the fastest way to modernize the whole car in an afternoon.
Raxiom Profile LED tails add a sequential signal to tie the build together.
How to Choose the Right Mustang Headlights
Start with your model year: 2015-2017 or 2018-2020. Then decide how far you want to go. If you want the maximum output and the full GT500-style light show, choose the AlphaRex NOVA full-LED projector — it is the only option here that replaces the low beam with LED. If you love the Shelby DRL look but want to save money, the Raxiom GT350/GT500 projector delivers the style for around $685. If your goal is simply to replace cloudy factory lenses with a clean OE-style unit, the Raxiom OEM HID-style projector at about $557 is the smart budget move. Finish the build with the Raxiom Profile LED tails for a cohesive front-to-back look.
Whichever you choose, all five are plug-and-play, in stock, and backed by NLP Performance support. Browse the full range in our headlights collection, and finish the look with a set of LED tail lights to match.
Frequently Asked Questions
Are LED headlights a plug-and-play upgrade on a 2015-2020 Mustang?
Yes. The AlphaRex NOVA and Raxiom projector headlights for the 2015-2020 Mustang are direct plug-and-play replacements that reuse the factory connectors, so no wire splicing is required. Most S550 owners complete the swap in under an hour with a socket set and a trim tool. A few base 2015-2017 cars that left the factory with halogen reflectors may need a simple adapter or a load resistor to prevent turn-signal hyperflash, which we can confirm by trim before you order.
Will 2015-2017 Mustang headlights fit a 2018-2020 Mustang?
No. Ford refreshed the S550 for 2018 with a new front fascia and hood line, so 2015-2017 and 2018-2020 headlights are not interchangeable. AlphaRex and Raxiom sell year-specific housings for each range — buy the 2015-2017 unit for pre-refresh cars and the 2018-2020 unit for refreshed cars. Always match the headlight to your exact model year.
What is a switchback DRL and sequential turn signal?
A switchback DRL is a daytime running light that glows white until you activate the turn signal, at which point that section switches to amber, then returns to white. A sequential turn signal lights its amber LEDs in an outward sweeping animation instead of blinking all at once, mimicking the factory Mustang and GT500 look. The AlphaRex NOVA headlights include both features built in.
Are AlphaRex and Raxiom Mustang headlights street legal?
AlphaRex NOVA headlights are built to DOT and SAE standards with a proper projector cutoff, which keeps glare down and keeps them street legal in most states. Raxiom projector headlights are also DOT-compliant OE-style replacements. As with any lighting upgrade, local inspection rules on color and beam pattern still apply, so verify your state's requirements before installing.
How much do 2015-2020 Mustang LED headlights cost?
Expect to pay roughly $557 to $1,250 per pair. Raxiom OEM-style HID projectors start around $557, the Raxiom GT350/GT500-style LED projector runs about $685, and the premium AlphaRex NOVA full-LED housings land around $995 for 2018-2020 cars and $1,250 for 2015-2017 cars. All five are in stock at NLP Performance.
Do LED headlights actually improve nighttime visibility?
Yes. A quality LED projector produces a whiter roughly 6000K beam with a sharper cutoff than a factory halogen's warm 3200K light, so the road ahead reads clearer and reflective signs pop earlier. The projector lens focuses the light into a defined pattern rather than scattering it, which improves distance vision without blinding oncoming traffic when the housing is aimed correctly.
