TMH 50 Count 2-Prong Wire Harness Roll Double Female Bullet Plug

In this review of the TMH 50 Count 2-Prong Wire Harness Roll, the bottom line is straightforward: this roll is for anyone who needs a quick, reliable way to wire multiple LED marker or clearance lights without fuss. The package arrives as approximately 25 ft of 18-gauge tinned copper wire with 50 double female bullet plugs spaced at 6.5 in, and the single biggest reason to buy is the plug-and-play convenience that eliminates many complex splices and connectors. For installers, fleet owners, and DIYers who value speed and corrosion resistance, this harness roll gets the job done.

Key Features

• Plug-and-play design: The double female bullet plugs let you connect 4.5 mm male plugs in seconds, reducing time spent on wiring runs.
• 50 plugs per roll: The roll contains fifty 2-prong female plugs across roughly 25 ft so you can cut to length for multiple lamps without buying separate leads.
• 18-gauge tinned copper: The wire uses tinned copper conductors that balance flexibility and conductivity for marker and clearance light circuits.
• Waterproof overmolded housing: The molded plug housings and PVC jacket provide corrosion resistance for outdoor use on trailers and trucks.
• 6.5 in spacing: Pre-spaced 17 cm leads between plugs make layout predictable for evenly spaced LED marker lights.
• One-year warranty: A full year warranty provides peace of mind and access to support if issues arise.

Who It's For

This harness roll is aimed at vehicle owners, mechanics, and small fleet operators who install or replace multiple LED marker or clearance lights and want to avoid soldering or complex splices. The built-in plugs are especially useful when retrofitting trailers or fitting side marker arrays where repeated identical connections are needed.

It is less appropriate for someone needing custom connectors other than 4.5 mm male bullet plugs or for installations that require heavier gauge cable or integrated fuses. For bespoke wiring looms with nonstandard spacing, a custom-cut loom might be a better choice.

Pros & Cons

Pros

• Fast, hassle-free installation with ready-made double female bullet plugs that save labor time.
• Good wire quality and waterproof overmolded plugs that resist corrosion in outdoor conditions.
• Generous roll length and plug count let you cut to size for many lights without waste.

Cons

• Spacing and connector type are fixed at 6.5 in and 4.5 mm female bullet plugs, so it is not universal for every wiring spec.

Its plug-and-play design, corrosion-resistant materials, and plentiful plug count make it strong value for installers who need predictable spacing and quick installs. Buyers who require different connector types or heavier wire should compare alternatives, but for standard marker light work this roll saves time and reduces wiring complexity.
