Partsam 4-inch round red LED trailer tail lights are a weather-sealed 8-piece kit that delivers stop, turn and tail functions with included rubber grommets and 3-prong wire pigtails for easy installation.

Whether you maintain an RV, pickup, trailer or commercial truck, reliable rear lighting is essential for safety and road compliance. This Partsam set supplies eight compact 4" red LEDs rated for 8–16 V DC systems, built to resist rain, dust and road debris. The kit comes with color-coded wiring and grommets so you can replace multiple lights quickly and get back on the road.

How do these lights perform in different weather and road conditions?

Each light features a fully sealed housing to keep moisture and dirt out, protecting the LEDs and connections. The durable construction helps maintain brightness and function after exposure to rain, snow or road spray.

• Sealed lens and housing to prevent water ingress
• 12 bright red LEDs per unit for consistent visibility
• Designed to resist dust, salt and debris from highways

What wiring and mounting parts are included for installation?

The kit includes rubber grommets and 3-prong wire pigtails so each light mounts and wires without hunting for extra components. Wiring is color-coded—white for ground, red for high/stop brightness and black for low/tail brightness—to simplify hook-up to standard trailer circuits.

• 8 rubber grommets for secure, vibration-resistant mounts
• 8 three-prong pigtails, color-coded for quick connections
• Compatible with common trailer wiring schemes and sockets

Will these lights fit my vehicle and electrical system?

These 4" round LEDs are made for a wide range of vehicles with 8–16 volt DC systems, including trailers, RVs, trucks, buses and utility vans. The compact round shape fits standard 4" cutouts and common mounting positions used on many rear lighting setups.

• Works across 8–16 V DC systems for broad compatibility
• 4-inch diameter matches common round tail light housings
• Ideal for single or multiple light replacements on trailers and rigs

How bright are these lights and what functions do they support?

Each lamp houses 12 red LEDs that provide clear stop, turn signal and tail illumination. The dual-intensity wiring supports a brighter stop/turn output and a lower-level tail/run light output for safe visibility day and night.

• 12 LEDs per light for strong, uniform red output
• High brightness for stop/turn; low brightness for tail lighting
• Instant LED response improves visibility compared with incandescent bulbs
