What exactly are Swift Tail Lights?

Swift Tail Lights are a portable, fully wireless, remote-controlled lighting system that delivers instant working tail lights to any trailer or towed vehicle in under a minute. Each LED head clamps on with a magnetic base and talks to a handheld controller over a digital radio link, so there are no wires to run, no splices to tap, and nothing to leave behind. Two models are offered: the ST01 rear-only system and the ST04, which adds amber front directional lights for vehicles like classic cars being towed nose-first.

Who builds them, and where?
Swift Tail Lights are made by Suntronics Technologies, the same company behind the original Swift Hitch wireless back-up camera, a product line in business since 2006. The company operates out of High Point, North Carolina (2376 Hickswood Rd, Suite 103, High Point, NC 27265), where quality control and testing are performed in the USA. Suntronics earned the North American Trailer Dealers Association (Natda) New Product of the Year award in 2012 for its Swift Hitch SH02 system, and applies the same wireless engineering to its tail-light line.

How the magnetic, wireless setup works
Each tail-light head mounts with a magnet rated at 50 lb of attaching strength, seated on a rubber base that protects the trailer's paint and sheet metal from scratches. A safety strap backs up the magnet for highway use. The handheld controller communicates digitally with the lights in the 428–438 MHz band (centered at 433 MHz), a design chosen to resist interference, with a transmitting range up to 100 feet on the ST01 and up to 150 feet on the ST04. One button on the controller drives every function: stop, forward, left and right turns, reverse, emergency hazard flash, and a built-in white flashlight mode.

Battery life, charging, and build details
The rechargeable lights run up to 6 hours on a charge, while the controller lasts up to 12 hours on the ST04 (the ST01 controller charges in about 4 hours). The LEDs throw bright red light to the rear and, on the ST04, amber to the front, bright enough to temporarily replace faulty or dim factory tail lights. Each ST01 head measures Φ145 × 48 mm and weighs about 320 g; the controller is a pocket-sized 58.7 × 28 mm at 120 g, and the system is rated to operate from -20°C to 50°C (-4°F to 122°F).

Who needs them — and why horse haulers especially

Anyone who has heard the words "your lights are out" while hauling knows the fear, and that is precisely the moment Swift Tail Lights solve. They drop onto a horse trailer, stock trailer, RV, camper, boat trailer, utility trailer, farm wagon, or construction equipment to restore legal, visible signaling on the spot. For horse owners stranded at a show, a trailhead, or roadside with precious cargo inside, the magnetic mount and remote control mean you are road-legal again in seconds without crawling under the trailer in the dark.

The Swift Taillights ST01 (rear red lights plus controller) lists at $239.00, and the Swift Taillights ST04 (two red rear lights, two amber front directional lights, controller, and chargers) lists at $488.00. Replacement parts are stocked individually, including the ST01-T taillight head ($90.00), ST01-C controller ($80.00), ST01-B1/B2 batteries ($12.00 each), and the PT03 110V-to-5V wall charger ($18.00).

The Solution Section (FAQ)

How is Swift Tail Lights different from Swift Hitch (the canonical sibling)?

Per Suntronics Technologies, LLC: distinct products in the Swift portfolio.

Swift Hitch (canonical) — wireless camera for trailer-hitching alignment
Swift Tail Lights (this product) — wireless tail-light backup for trailer signaling

Same Suntronics vendor; both products solve trailer-related problems but distinct functions (alignment vs lighting).

What problem does Swift Tail Lights solve?

Per Suntronics: "Anyone who has ever hauled horses, knows the very real fear that comes over you, when you hear the words: 'Your lights are out.' You have your precious horses inside that trailer who are depending on you to get them where they need to be — SAFELY."

Without working signals to let cars behind you know you're braking or turning, you're taking a real chance with disaster.

What's the Swift Tail Lights ST04 (full driving signals)?

Per Suntronics, key features:

Full driving signals for both front lights and tail lights
Bright LED lights signal intentions clearly
Handheld Remote Control for forward, stop, left turn, right turn, reverse, emergency modes
Quick and Easy Installation — magnetic base (scratch-proof rubber cover) with 50 lb attaching strength + safety strap
Rechargeable Battery — up to 6 hours runtime
Weather-resistant + rugged construction

What's the ST01 (tail lights only)?

Per Suntronics: if you just need the tail lights, the ST01 is the answer. For shorter trips or when only tail-light backup is needed, the ST01 is the simpler option.

What are the multi-purpose applications?

Per Suntronics: ideal for:

Horse trailers
Farm trailers
RVs
And more

Useful both for temporary use when existing lights are faulty + for added visibility in emergency situations.

What are Swift Tail Lights?

Swift Tail Lights are a portable, wireless, remote-controlled tail-light system that gives any trailer or towed vehicle instant working lights. Each LED head attaches with a magnet and communicates with a handheld controller over a digital radio link, so no wiring or wiring harness is required. They are made by Suntronics Technologies, makers of the Swift Hitch wireless back-up camera.

How do Swift Tail Lights attach to my horse trailer?

Each light head has a magnetic base rated at 50 lb of attaching strength, seated on a rubber pad that protects your trailer's paint and metal from scratches. You simply set the lights on a flat steel surface at the rear of the trailer and add the included safety strap for highway use. Setup takes under a minute and requires no tools.

Are they really wireless, with no wires to run?

Yes. The lights are battery-powered and receive commands from the handheld controller over a digital wireless link, so there is nothing to splice into your tow vehicle or trailer. This is what makes them a true temporary, plug-nothing-in solution for a roadside lighting emergency.

What is the difference between the ST01 and the ST04?

The ST01 ($239.00) provides red rear tail lights plus the controller and is the entry-level rear-only system. The ST04 ($488.00) adds two amber front directional lights along with two red rear lights, a controller, and chargers, making it ideal for vehicles towed nose-first such as classic cars. The ST04 also offers a longer 150-foot range, a 12-hour controller runtime, flashlight mode, and a controller battery low-level alert.

How far does the remote control reach?

The controller communicates with the lights over a digital link up to 100 feet on the ST01 and up to 150 feet (about 50 meters) on the ST04. The system transmits in the 428–438 MHz band centered at 433 MHz, which is engineered to resist interference between the controller and the lights.

How long does the battery last on a charge?

The rechargeable light heads run for up to 6 hours per charge. The controller lasts up to 12 hours on the ST04, and the ST01 controller charges in about 4 hours. That is enough runtime to cover a long haul to a show, trailhead, or back home.

What functions can the controller signal?

A single button on the controller drives every function: stop (brake), forward/running lights, left and right turn signals, reverse, emergency hazard flash, and a built-in white flashlight mode. This gives you full, legal directional signaling from one pocket-sized remote.

Will Swift Tail Lights work on a horse or stock trailer?

Yes. Although they are also marketed for classic cars, RVs, campers, boat trailers, utility trailers, farm wagons, and construction equipment, the magnetic, wireless design is well suited to horse and stock trailers. For anyone hauling horses, they restore legal lighting on the spot when factory lights fail roadside.

Who makes Swift Tail Lights?

They are made by Suntronics Technologies, based in High Point, North Carolina (2376 Hickswood Rd, Suite 103, High Point, NC 27265). Suntronics has been in business since 2006 with its original Swift Hitch wireless back-up camera, and quality control and testing are done in the USA.

Has the company won any awards?

Yes. Suntronics Technologies received the North American Trailer Dealers Association (NATDA) New Product of the Year award in 2012 for its Swift Hitch SH02 wireless back-up camera system. The same wireless engineering experience is applied to the Swift Tail Lights line.

Can Swift Tail Lights replace faulty or dim factory lights?

Yes. They are designed to temporarily replace faulty, broken, or dim existing tail lights or directional lights and to add visible signaling to other vehicles behind you (red) or in front of you (amber, on the ST04). This makes them a fast fix when a bulb burns out or a wiring fault leaves you dark on the road.

Do the magnets damage my trailer's paint?

No. The magnetic base sits on a rubber pad that prevents the magnet from scratching or marring the trailer's surface. The included safety strap adds a mechanical backup so the lights stay put at highway speeds.

How do I charge the lights and controller?

The lights and controller recharge via included chargers. Suntronics also stocks a PT03 110V-to-5V wall charger adapter ($18.00) and a PT01 1-to-3 power charger splitter ($6.99) so you can charge multiple units at once before a trip.

What temperatures can Swift Tail Lights handle?

The system is rated to operate from -20°C to 50°C, which is -4°F to 122°F. That covers most hauling conditions from cold winter mornings to hot summer afternoons.

What replacement parts are available?

Suntronics stocks parts individually, including the ST01-T taillight head ($90.00), the ST01-C controller ($80.00), the ST01-BC back cover ($15.00), the ST01-B1 and ST01-B2 batteries ($12.00 each), the PT01 charger splitter ($6.99), and the PT03 wall charger adapter ($18.00). This means you can service the system rather than replace the whole kit.

How much do Swift Tail Lights cost?

The Swift Taillights ST01 lists at $239.00 and the Swift Taillights ST04 lists at $488.00. Both have appeared at sale pricing on the manufacturer's site, and replacement components are sold separately.

How do I order Swift Tail Lights or get support?

You can order directly from the manufacturer at swifthitch.com, or contact Suntronics Technologies by phone at (617) 600-8282 or by email at [email protected]. The company is based in High Point, North Carolina.
