ONLINE LED STORE 3/4" Red Round LED Trailer Marker Lights 10pc — DOT-compliant, IP67 sealed, 180° visibility

The TRUE MODS 3/4" red round LED trailer marker light is a compact, DOT-compliant clearance and side marker designed for semi trucks and trailers, sold in a 10-piece set for reliable, low-maintenance visibility.

These small-but-bright lights from ONLINE LED STORE are built to meet DOT FMVSS-108 standards while providing flexible mounting and two brightness settings. Their sealed construction and three-wire design let you use them as clearance lights, side markers, or auxiliary turn/brake signals. Designed for fast retrofit or new installs, they help maintain compliance and improve nighttime conspicuity without complicated wiring or cutting corners.

How do these lights improve visibility on long-haul routes?

The TRUE MODS LED markers produce a wide 180-degree light arc and are SAE P2 PC rated, so they’re visible from more angles than narrow-beam bulbs. That increased spread helps other drivers see trailer extremities and reduces blind spots at intersections and lane changes.

• 180-degree visible arc for side and corner coverage
• Red lens tuned for rear/side marker signaling
• SAE P2 PC rating for reliable reflectivity and spread

What makes these marker lights durable and weatherproof?

Each unit is IP67-rated and fully sealed to resist water and dust intrusion, so they remain functional after heavy rain, splashes, or brief submersion. The rugged housing and quality seals reduce corrosion and failure points common with cheaper fixtures.

• IP67 fully submersible rating for wet conditions
• Sealed housing to prevent moisture and debris entry
• Longer service life compared with non-sealed alternatives

Can these LEDs replace multiple lights and how easy is installation?

The three-wire design with two brightness levels offers multi-function capability—useable as clearance, side marker, or supplemental brake/turn signals depending on wiring. They install quickly with a standard 3/4" hole and include pre-attached .180" bullet connectors for a no-screw grommet setup.

• Three-wire wiring for dim/bright or multi-function use
• Standard 3/4" form factor for fast retrofit holes
• Pre-attached .180" bullet connectors for quick hookups

Are these lights legal for road use and suitable for commercial fleets?

Yes—the TRUE MODS markers meet DOT FMVSS-108 requirements, so they satisfy U.S. federal visibility and build standards for clearance and side marker lighting. That makes them a practical option for fleets, owner-operators, and anyone needing compliant replacements.

• DOT FMVSS-108 compliant for legal highway use
• Sold as a 10-piece pack to outfit multiple mounting points
• Consistent output and ratings useful for fleet maintenance

Who is this for: These TRUE MODS 3/4" red round LED marker lights are aimed at truck drivers, trailer owners, and fleet managers who need DOT-compliant, low-profile marker lights that install quickly and withstand harsh weather. They’re ideal for routine replacements, whole-trailer retrofits, or upgrades where improved side and corner visibility and sealed durability are priorities. If you want reliable, multi-function marker lights that minimize downtime and meet legal standards, this 10-piece set from ONLINE LED STORE is engineered for that purpose.
