Partsam 4" Round Red LED Trailer Tail Lights 8-Pack — 12-LED Stop/Turn/Tail, Sealed with Grommets & 3-Prong Pigtails

Partsam 8-pack 4" round red LED trailer tail lights are sealed, multi-function stop/turn/tail lamps supplied with rubber grommets and 3-prong wire pigtails for quick replacement on trailers, RVs, and trucks.

These 4-inch LED assemblies deliver visible stop, turn and tail signaling using 12 bright red LEDs in each lens and are built to withstand road conditions. The kit includes everything needed to swap out worn lights: matching rubber grommets for secure mounting plus color-coded pigtails for straightforward wiring. They work across a broad DC range so you can use them on many vehicle classes without an additional converter.

How bright and visible are these lights on the road?

Each lamp contains 12 high-intensity red LEDs arranged to provide clear stop, turn, and tail illumination. The LEDs offer consistent light output and are easier to spot than incandescent bulbs at a distance, which helps other drivers identify braking and turning actions sooner.

• 12 red LEDs per light for strong visibility
• Distinct stop, turn, and tail output patterns
• Even illumination across the 4" lens

Will these lights survive rain, mud, and highway debris?

The housings are fully sealed to keep out water, dust, and road grit, making them suitable for all-weather use. The durable construction reduces the risk of moisture-related failures and helps maintain reliable operation through seasons and rough conditions.

• Fully sealed assembly resists water and dust intrusion
• Rugged exterior to resist road debris impact
• Designed for continuous outdoor exposure

How easy is installation and wiring for an average DIYer?

Installation is straightforward: each light comes with a rubber grommet for a snug mount and a 3-prong pigtail with color-coded wires for quick connection. The white wire is ground, red is high-brightness (brake/turn), and black is low-brightness (tail), which simplifies matching to existing trailer wiring.

• Includes rubber grommets for secure mounting without extra hardware
• 3-prong wire pigtails with color coding for fast hookups
• Compatible with common trailer light locations and mounting holes

Are these lights compatible with my vehicle’s electrical system?

These LEDs operate across an 8–16 V DC range, so they fit the electrical systems of most trailers, RVs, trucks, semis, buses, and utility vans without additional adapters. Always verify your vehicle’s wiring scheme and consult a wiring diagram if your setup is nonstandard.

• Wide voltage compatibility: 8–16 V DC
• Works on trailers, RVs, trucks, and larger commercial vehicles
• Color-coded leads match standard automotive wiring conventions

Who is this for? This 8-piece Partsam kit is aimed at vehicle owners, fleet managers, and DIY mechanics who need a complete, plug-and-play replacement set of red 4" LED tail lights. It’s ideal when you want weatherproof, energy-efficient signaling lamps that simplify installation and restore clear brake/turn/tail functionality across trailers, campers, and work trucks.
