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

TMH 20 Count 2-prong wire harness roll is a ready-to-cut, 18-gauge tinned-copper lead set with double female 4.5mm bullet plugs spaced 6.5" apart for fast, waterproof LED marker and clearance light hookups.

This harness roll gives technicians, DIYers, and fleet owners a pre-assembled solution for repeating light connections without stripping and soldering each joint. The roll contains twenty molded double-female bullet plugs on an approximately 10-foot length of 18 AWG PVC-jacketed wire, so you cut the harness to the exact number of fixtures required. The plugs are waterproof and designed to fit 4.5mm (0.180") male bullets, simplifying replacement and installation of LED marker or clearance lights on trailers, trucks, RVs, and marine applications.

How does this harness speed up LED marker and clearance light installation?

Pre-spaced plugs eliminate repeated wire termination steps and let you plug lights in at consistent intervals. Installers save time by trimming to length and plugging straight into male bullets or standard connectors, reducing the need for crimping, soldering, or shrink tubing for each light.

• 20 pre-molded double-female bullet plugs on an approximate 10-foot roll
• 6.5" (17 cm) spacing between plugs for uniform light placement
• Fits 4.5mm (0.180") male bullet plugs for common LED lights
• Cut-to-length design lets you prepare harnesses for any run quickly

Is the wire durable and suitable for outdoor or marine conditions?

Yes — the conductors are 18-gauge tinned copper and the plugs are overmolded in waterproof PVC, giving improved corrosion resistance in wet environments. The PVC jacket helps protect against abrasion and UV exposure compared with bare, unprotected wiring commonly used in temporary setups.

• 18 AWG tinned copper conductors resist corrosion
• Overmolded, waterproof plug housings reduce moisture entry
• Durable PVC jacket provides abrasion and weather protection
• Reliable for road, trailer, RV, and marine use when properly routed

What wiring details and compatibility should I know before buying?

The harness uses standard 18 AWG wire and double-female 4.5mm bullet plugs, which match many LED marker and clearance light males. The 6.5" center spacing suits most side- and rear-marker layouts, and the roll format lets you adapt it to custom spacing by cutting and sealing ends.

• Wire gauge: 18 AWG (tinned copper) for good current capacity
• Plug size: 4.5mm (0.180") double-female bullet compatible
• Spacing: 6.5" (17 cm) between each female plug lead
• Length: approx. 10 feet total, 20 plugs per roll; cut as needed

What after-sales support and guarantees come with this product?

TMH backs the harness roll with a one-year warranty and a professional support team to address fitment or quality questions. If a defect appears within the warranty period, TMH provides guidance and replacement options to minimize downtime on installs.

• 1-year limited warranty for manufacturing defects
• Customer support for compatibility and installation questions
• Clear specifications to confirm fit before installation

Who is this for: This harness is ideal for electricians, trailer and fleet maintenance shops, RV owners, and DIY installers who want a clean, repeatable way to wire multiple side marker or clearance lights quickly. Choose this roll when you need corrosion-resistant, pre-spaced connections that reduce assembly time and yield consistent results across multiple fixtures.
