Truck Universal Small Taillight American Version, 16 LED Dual Color Rubber Ring Round Light ,12V, 4-pack

If your work truck, semi, or trailer is still running dim incandescent taillights — or worse, cracked, water-logged housings that put you out of compliance — these 16 LED Dual-Color Round Taillights are the no-compromise fix. Sold as a complete 4-pack, this kit lets you refresh every primary rear light position in a single order, so you leave the parts house with exactly what you need. Compatibility Engineered to the American truck lighting standard, these universal round taillights are built to fit the widest possible range of commercial and light-duty vehicles on US roads today. They are a direct drop-in for standard round cutout diameters found on Freightliner Cascadia, M2, and Business Class trucks; Kenworth T680 and W900 semis; Peterbilt 389 and 579 models; and most major box truck and step-van body styles. Flatbed trailers, utility trailers, gooseneck trailers, and fifth-wheel setups that use round fender-mount or surface-mount light positions are excellent candidates. They also work as supplemental rear marker or auxiliary lights on popular pickup platforms — Ford F-150, F-250, and F-350 Super Duty; RAM 1500, 2500, and 3500; Chevrolet Silverado 1500 and 2500HD; and GMC Sierra — when added to aftermarket truck bodies, toolboxes, or trailer hitches. Always measure your existing cutout or mounting hole diameter against the product dimensions listed in the specs section below before ordering. Universal fit means broad coverage, and a quick measurement guarantees a rattle-free, watertight installation. Benefits • Dual-color, code-compliant output — red stop/tail and amber turn signals combined in one compact round lens, eliminating the need for separate single-function lights and simplifying your wiring harness. • Dramatically brighter than incandescent — 16 individual LEDs per housing push substantially more candela output than old-style bulbs, making your rig visible at highway distances even in heavy rain or low-light conditions. • Rubber ring gasket protection — the integrated rubber ring seals the housing perimeter against rain, road spray, mud, and vibration, locking out the moisture intrusion that corrodes sockets and kills electrical connections over time. • 12V DC native operation — works plug-and-play with virtually every truck, trailer, cargo van, and commercial fleet electrical system in North America; no voltage converters or relay kits required. • 4-pack value bundle — covers all four primary rear light positions at once, so you avoid mismatched lens colors or piecemeal upgrades that look unprofessional on a commercial rig. • Long LED service life — solid-state LED construction means no filament to vibrate loose on rough roads or job-site terrain, reducing maintenance stops and replacement costs over the working life of your vehicle. Technical Specs • LED count: 16 LEDs per light unit • Colors: Red (stop/tail) and Amber (turn signal) — dual function • Operating voltage: 12V DC • Housing material: ABS plastic with integrated rubber ring gasket • Lens material: Polycarbonate-style tinted lens • Mounting style: Round surface-mount or flush-mount (verify cutout diameter) • Quantity: 4 lights per pack • Approvals: Designed to American truck lighting standard for road-legal rear signaling • Operating temperature range: Suitable for standard North American climate ranges Materials & Build Quality These round taillights are constructed from impact-resistant ABS plastic housing paired with a durable polycarbonate-style lens that resists UV yellowing and cracking — a common failure point on cheap replacement lights left exposed to years of sun, road salt, and highway grime. The rubber ring gasket is the real workhorse of this design. Molded to hug the mounting surface, it compresses evenly when the housing is fastened down, creating a circumferential seal that blocks water ingress at the perimeter. On commercial trucks and trailers that run through all-weather conditions — from January sleet on I-90 to August heat on I-10 — that seal is the difference between a light that lasts a season and one that lasts years. The LED array itself is mounted to a dedicated circuit board inside the housing, eliminating the vibration-induced filament failures that plague incandescent units on trucks operating over rough terrain, dock plates, and unpaved job sites. Every component is selected for the duty cycle demands of working vehicles, not passenger cars. Installation Guide Installing these universal round taillights is a straightforward job most owner-operators and fleet mechanics can complete with basic hand tools. Step 1: Disconnect the vehicle's battery or the trailer's breakaway battery to prevent accidental shorts during wiring work. Step 2: Remove the existing taillight by unscrewing the retaining hardware and unplugging the connector from the wiring harness. Step 3: Measure the existing cutout or mounting hole diameter and confirm it matches the product dimensions — this is the most important step for a clean, rattle-free fit. Step 4: Feed the new light's pigtail wires through the mounting hole or along the surface routing path. Step 5: Identify the vehicle wiring: ground (white or black), stop/tail (red), and turn (yellow/amber). Match to the corresponding light wires using weatherproof butt connectors or a trailer wiring plug. Step 6: Position the rubber ring gasket against the mounting surface and press the housing firmly into place. Step 7: Secure with the included or existing mounting hardware, being careful not to overtighten and distort the gasket. Step 8: Reconnect power and test all functions — stop, running, and turn — before closing up the body panels or fenders. The whole job typically takes under 30 minutes per light position.
