Partsam 4pc 6" Oval Red LED Sealed Trailer Lights — Flush-Mount Stop/Turn/Tail, Waterproof DOT-Compliant

These 6-inch oval LED lamps combine three lighting modes (tail, stop/brake, and turn) in one sealed housing, offering bright SMD illumination, a 3-pin watertight connector, and rubber grommets for surface installation. Designed for 12–16V vehicle electrical systems, the lights are suitable for commercial and recreational trailers, trucks, and specialty vehicles that require rugged, visible rear lighting that resists moisture and road grit.

How bright are these LEDs and can they show multiple functions?

Each lamp contains 10 high-quality SMD LEDs beneath a red lens, providing a clear high-brightness output for brakes and turn signals and a lower-intensity mode for running lights. They operate on a 3-wire system so you can switch between brightness levels for different functions.

• 10 SMD red LEDs per light for strong rear illumination
• Two brightness levels: low for tail, high for brake/turn
• 3-wire wiring: ground, low, and high brightness leads

Are these lights easy to install and weatherproof?

Installation is straightforward: the lamps mount flush with supplied rubber grommets and connect using the included 3-pin watertight plug and pigtail wires. The sealed housing and IP67-style protection help prevent water ingress so lights remain functional in wet conditions.

• Includes grommets for surface/flange mounting
• 3-prong watertight plug attached to wires for quick hookup
• Sealed construction resists water and road debris

Which vehicles and wiring systems are these lights compatible with?

These oval LEDs work with most 12–16V DC systems found on trucks, trailers, buses, and many heavy-duty vehicles. They suit fleets and owners who need DOT-compliant rear signaling across a wide variety of makes and models.

• Compatible with semi-trailers, pickup trucks, utility trailers, buses, and more
• Works with common 12V automotive electrical systems (up to 16V)
• Can replace standard oval sealed lamps on many vehicle brands

What are the physical size and wiring details I should know?

The lamp measures approximately 7 1/4" long by 3 1/10" wide and includes wiring guidance to reduce guesswork during installation. A recommended hole size for the surface mount and grommet is provided for correct fit and secure sealing.

• Overall lamp size: about 7.25" L x 3.1" W
• Surface mount hole dimensions: 6.6" x 2.5" x 1.75"
• Wiring: white = ground, red = high brightness, black = low brightness

Who this is for: installers, fleet managers, and trailer owners who need rugged, multi-function rear lights that are simple to mount and resistant to harsh road and weather conditions. If you want sealed, DOT-compliant oval LED tail lights that offer bright brake/turn signals, low-intensity running lights, and straightforward wiring with a watertight connector, this 4-piece Partsam kit fits many heavy-duty and recreational vehicle applications.
