TRUE MODS 2pc 3/4" Inch Round Amber Trailer 12V LED Marker Light – In-Depth Review
If you’ve ever dealt with dim, unreliable, or water-damaged trailer lights, you already know how frustrating (and risky) poor visibility can be. Whether you’re hauling equipment, towing a trailer after dark, or simply trying to stay compliant with road safety regulations, small details like marker lights matter more than most people realize. That’s where the TRUE MODS 2pc 3/4" Inch Round Amber Trailer 12V LED Marker Light comes in.
These compact amber LED marker lights are designed for trailers, trucks, and utility vehicles that need dependable visibility, multiple lighting functions, and long-term durability. On paper, they promise DOT compliance, better side visibility, multiple wiring options, and full waterproofing—all at a very accessible price point. In this detailed review, I’ll walk through exactly what these lights offer, who they’re best for, and where they might not be the perfect fit.
Quick Product Overview
The TRUE MODS 3/4-inch round amber LED marker lights are small, semi-spherical clearance and side marker lights built for 12V systems. This 2-piece set uses a three-wire design that supports dual brightness levels, allowing the lights to function as clearance lights, side markers, auxiliary turn signals, or supplemental brake lights depending on how they’re wired.
They are DOT FMVSS 108 compliant and SAE P2 PC rated, meaning they meet strict visibility and safety standards for road use. With an IP67 waterproof rating and a no-screw grommet-style installation, these lights are clearly aimed at drivers and fleet owners who value quick installs and long-term reliability.
Key Features Explained in Detail
DOT FMVSS 108 Compliance
One of the most important features of these TRUE MODS marker lights is their DOT FMVSS 108 compliance. This certification ensures the lights meet federal standards for visibility, durability, and performance. In real-world terms, that means you can install them with confidence knowing they are legal for road use and built to withstand daily driving conditions.
For commercial drivers, fleet operators, or anyone hauling equipment regularly, compliance isn’t optional—it’s essential. Using compliant lighting reduces the risk of citations and improves overall road safety.
SAE P2 PC Rating and 180-Degree Visibility
These lights are SAE P2 PC rated, producing a wide 180-degree arc of light. When mounted on the 45-degree corner of a trailer or truck, they can serve as both a clearance light and a side marker light at the same time. This dual-purpose design is especially useful on compact trailers or builds where mounting space is limited.
Better side visibility means other drivers can clearly see your vehicle’s outline, especially at night or in low-light conditions like rain or fog. It’s a small upgrade that can make a big difference in real-world driving safety.
Three-Wire Design with Dual Brightness Levels
Unlike basic two-wire marker lights, this TRUE MODS model features a three-wire configuration that supports two brightness levels. This added flexibility allows the lights to be used in multiple ways: as standard side marker lights, clearance lights, auxiliary turn signals, or even supplemental brake lights depending on how you wire them.
This versatility is particularly helpful for custom trailer builds or repairs where you want one light to serve multiple functions. Instead of buying separate lights for each purpose, you can simplify your setup with a single, multi-functional unit.
IP67 Waterproof and Fully Submersible
Trailer lights are constantly exposed to rain, road spray, dust, and sometimes complete submersion during boat launches. These marker lights are rated IP67, meaning they are fully sealed and submersible. The internal components are protected from moisture intrusion, which is one of the most common causes of lighting failure.
Over time, this level of sealing translates into fewer replacements, less maintenance, and more consistent performance in all weather conditions.
Quick, No-Screw Installation
Time spent in the garage is time you’re not on the road. These lights use a standard 3/4-inch mounting size with a no-screw grommet-style install. Combined with pre-attached .180-inch bullet connectors, installation is straightforward and fast.
This design is ideal for quick replacements or upgrades, especially when you’re working on multiple trailers or vehicles and want to minimize downtime.
Benefits for Users
The biggest benefit of the TRUE MODS 3/4-inch amber LED marker lights is peace of mind. You get compliant, highly visible lighting that works reliably in harsh conditions. The wide visibility arc improves safety, while the multi-function wiring adds flexibility for different setups.
For everyday users, these lights reduce the hassle of frequent replacements caused by water damage or poor build quality. For professionals, they help keep vehicles compliant and road-ready with minimal installation time.

How to Use / Setup / Best Practices
Installation starts by ensuring your mounting hole matches the standard 3/4-inch size. Insert the light into the grommet-style opening until it sits securely.
