Jammy J-75L LED Trailer Tail Light | 8" Submersible Stop/Turn/Tail + License Plate | Driver Side Left
Jammy J-75L LED Trailer Tail Light — 8" Submersible Stop/Turn/Tail + License Plate, Driver Side The Jammy J-75L is a fully submersible 8-inch rectangular LED trailer tail light com bining stop, turn, tail, and integrated license plate illumination in a single sealed unit. Built with 13 high-output LED diodes and marine-grade tinned wiring, the J-75L is engineered for boat trailers, utility trailers, and any application where water, salt, and road grime are a constant — including full submersion at the boat ramp. The J-75L mounts on the driver side (street side / left side) of your trailer and includes a built-in license plate light — a legal requirement on the driver side of all trailers. For the curbside (passenger/right side) without license plate illumination, see the Jammy J-75. Why Choose the Jammy J-75L?

The J-75L uses the industry-standard 8" rectangular footprint with 2-bolt / 2" center-spacing mount — the same pattern used by Wesbar, Peterson, and Optronics on this light class. It is a direct aftermarket replacement for the following: Brand Part Number Notes Wesbar 3504 / 403076 Driver side with license plate — over 80" wide trailers Wesbar 407540 LED waterproof 7-function driver side with license plate — over 80" Peterson M456L 8" rectangular submersible driver side with license plate — over 80" Optronics ST17RB / STL17RB Incandescent and LED driver side with license plate — over 80" Magic Tilt PL1181 / PL1183 8" rectangular LED driver side — Jammy-manufactured OEM Karavan 205-00163-NA / 205-00387-NA LED combination driver side with license plate — over 80" wide trailers Important: The J-75L replaces the driver side (left/street side) only. For the curbside (passenger/right side) without license plate light, you need the Jammy J-75 (cross-references: Wesbar 3554 / 403026, Peterson M456, Optronics ST16RB / STL16RB). Not sure if this replaces your light? Measure your existing housing: if it's approximately 8" long x 2-3/4" to 2-7/8" tall with studs on 2" centers and a license plate bracket on the driver side, the J-75L is your replacement. Trailer Compatibility — Boat & PWC Applications The J-75L is the factory-style driver-side replacement light for dry-launch style boat trailers — the low-profile rectangular design used by the major marine trailer manufacturers. If your boat or PWC trailer is over 80" wide and uses the 2-bolt rectangular mount, this is your driver-side light.

Common Boat & PWC Types The J-75L is commonly used on trailers hauling: bass boats, pontoon boats, aluminum fishing boats, center console boats, bowriders, ski boats, deck boats, Boston Whaler, Sea Ray, Lund, Tracker, Carolina Skiff, Jon boats, Sea-Doo, Yamaha WaveRunner, Kawasaki Jet Ski, and similar PWC / personal watercraft. Saltwater use: The J-75L's epoxy-sealed SMD diodes, marine-grade tinned wiring, and stainless mounting hardware make it one of the few lights genuinely rated for repeated saltwater immersion. It is widely used by anglers and boaters who launch in coastal and tidal environments. Verify fit before ordering: Confirm your trailer uses an 8" rectangular light housing with 2-stud mount on 2" centers. If your trailer uses a different spacing or a 6" rectangular housing, see our other trailer tail lights for the right fit. 💡 Pro Tips The J-75L installs in minutes using the two pre-installed mounting studs and included hardware. Studs are spaced 2 inches on center to match standard trailer light mounts. The 14-inch pre-wired leads connect directly to your trailer's existing wiring: Brown → Tail / running lights Yellow → Stop / turn signal White → Ground Black → License plate light No special tools required. Compatible with standard 4-pin flat and 5-wire trailer wiring harnesses. The license plate light lead connects to your trailer's running light circuit. Is the J-75L truly submersible? Yes. The J-75L uses a fully sealed epoxy housing with tinned wiring, making it safe for complete water immersion — including repeated dunking at the boat ramp. What's the difference between the J-75L and J-75? The J-75L is the driver side (left/street side) light and includes an integrated license plate light. The J-75 is the curbside (passenger/right side) version without the license plate light. Most trailers require one of each. Will this replace my existing Optronics or Peterson driver-side rectangular tail light? In most cases, yes — as long as your current light uses an 8" rectangular housing with 2-stud / 2" center mount and an integrated license plate bracket. Measure your existing cutout and stud spacing to confirm before ordering. Will this fit my Karavan or Magic Tilt trailer? Yes — the J-75L is the direct OEM replacement for Magic Tilt trailers and a confirmed fit for Karavan trailers using the standard 2-bolt 8" mount. See the compatibility table above for full details. Is the J-75L DOT legal? Yes. The J-75L is DOT and SAE approved, meeting FMVSS-108 requirements for stop, turn, tail, and license plate illumination on trailers. Do I need one or two? Most trailers over 80" wide require a matched pair — the J-75L (driver side with license plate) and the J-75 (curbside without license plate). Both are available individually or as a kit. Questions?
