Jammy J-75 LED Trailer Tail Light — 8" Submersible Stop/Turn/Tail, Curbside

The Jammy J-75 is a fully submersible 8-inch rectangular LED trailer tail light combining stop, turn, and tail functions in a single sealed unit. Built with 13 high-output LED diodes and marine-grade tinned wiring, the J-75 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-75 mounts on the curbside (passenger side) of your trailer. For the driver side with integrated license plate illumination, see the Jammy J-75L.

Why Choose the Jammy J-75?

• Fully submersible — sealed epoxy construction handles repeated water immersion; no fogging, no corrosion
• 13 high-output LEDs — brighter stop and turn output than incandescent, visible in direct sunlight
• DOT / SAE compliant — meets FMVSS-108 standards for stop, turn, and tail functions
• Marine-grade tinned wiring — resists oxidation and corrosion in saltwater environments
• Direct replacement fit — 2-stud mount with 2" center spacing matches most standard 8" trailer light cutouts
• Low power draw — LED efficiency reduces load on your tow vehicle's electrical system
• Plug-and-play wiring — standard brown/yellow/white lead wires connect directly to all common trailer wiring harnesses

Cross-Reference — What Does the Jammy J-75 Replace?

The J-75 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:

Important: The J-75 replaces the curbside (passenger/right) side only. For the driver side with license plate light, you need the Jammy J-75L (cross-references: Wesbar 3504 / 403076, Peterson M456L, Optronics ST17RB / STL17RB).

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, the J-75 is your replacement.

Trailer Compatibility — Boat & PWC Applications

The J-75 is the factory-style 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 light.

Confirmed Compatible Trailer Brands

Common Boat & PWC Types

The J-75 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-75'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-75 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

No special tools required. Compatible with standard 4-pin flat and 5-wire trailer wiring harnesses.

Is the J-75 truly submersible?
Yes. The J-75 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-75 and J-75L?
The J-75 is the curbside (passenger side) light. The J-75L is the driver-side version and includes an integrated license plate light. Most trailers require one of each.

Will this replace my existing Optronics or Peterson rectangular tail light?
In most cases, yes — as long as your current light uses an 8" rectangular housing with 2-stud / 2" center mount. Measure your existing cutout and stud spacing to confirm before ordering.

Will this fit my Karavan or Magic Tilt trailer?
Yes — the J-75 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-75 DOT legal?
Yes. The J-75 is DOT and SAE approved, meeting FMVSS-108 requirements for stop, turn, and tail functions on trailers.

Do I need one or two?
Most trailers over 80" wide require a matched pair — the J-75 (curbside) and the J-75L (driver side with license plate light). Both are available individually or as a kit.
