TMH 20-Count 2-Prong Wire Harness Roll — 18 AWG, 6.5 in Spacing, Waterproof Double Female Bullet Plugs

TMH 20-count 2-prong wire harness roll is a pre-wired strip of 18‑gauge double female bullet plugs spaced 6.5" apart to speed up LED marker and clearance light installations.

If you install multiple LED marker lights, trailer lights, or clearance lamps, running individual wires and making separate connectors can be time consuming. This roll bundles twenty double-female bullet plug assemblies on a continuous 18 AWG tinned-copper conductor so you can cut the exact length you need, plug in lights quickly, and keep connections neat and weather resistant.

How does this harness make LED marker light wiring faster?

The harness removes repetitive crimping, soldering, or taping by providing factory-molded double female bullet plugs every 6.5 inches. Rather than build each pigtail from scratch, you cut the roll, route it along the vehicle or trailer, and plug lights straight into the female sockets.

• Pre-molded plugs for rapid plug-and-play hookups
• 6.5" (17 cm) spacing matches common marker light intervals
• Twenty plugs on the roll — cut to any required length
• Reduces time spent on repetitive termination work

What are the wiring and durability specifications?

Each lead uses 18-gauge tinned copper for a balance of flexibility and current capacity appropriate for marker and clearance lamps. The plugs are over-molded in waterproof PVC to resist corrosion and moisture at the connection points, and the double female configuration accepts 4.5mm (0.180") male bullet pins.

• 18 AWG tinned copper conductor for reliable conductivity
• Waterproof over-molded plug housing to limit corrosion
• Compatible with 4.5mm (0.180") male bullet connectors
• PVC jacket for abrasion resistance and outdoor use

How do I cut, route, and use the roll during installation?

Measure the distance between lights, cut the roll at your desired length, and secure the wiring along the frame or body using clamps or zip ties. At each light location, plug the light's male bullets into the double female sockets; if necessary, strip and terminate the feed ends for power and ground connections.

• Cut anywhere on the roll to create custom pigtails
• Secure with clips or zip ties to prevent chafing
• Plug male bullet terminals directly into female sockets
• Strip and attach feed wires to the roll ends for power

It’s designed for anyone who wants to save time on repetitive wiring tasks, keep connections uniform and weather-resistant, and customize harness length without building each pigtail individually. The included 20 plugs and one-year warranty make it suitable for trailer builders, RV owners, truck customization, and light-duty commercial applications where quick, reliable hook-ups are required.
