Partswcgg LED Trailer Tail Lights 4-Inch Round Red — 4-Pack, 24-LED IP65 Waterproof Flush-Mount

Partswcgg 4-pack 4-inch round red LED trailer tail lights — 24 LEDs each, IP65 water-resistant, flush-mount with rubber grommets and 3-prong 12V pigtails included.

These 4-inch round LED tail lights from Partswcgg combine compact size with high-visibility LEDs and a sealed design for exterior vehicle use. Each lamp houses 24 LED chips that draw less power than incandescent bulbs while offering brighter, crisper illumination for stop, turn, brake, tail, and marker functions. The package includes four lights, matching rubber grommets sized for flush mounting, and three-prong wiring pigtails so you have everything needed to install them on trailers, trucks, RVs, and a wide range of 8–16V DC vehicles.

How do these lights perform in wet or dusty conditions?

Partswcgg lights are built with an IP65-rated seal that protects against dust and water spray. They are suitable for exterior use on trailers and trucks where exposure to rain, road spray, and grime is common — but they are not designed for continuous submersion.

• IP65 water-resistant housing for protection from rain and splashes
• Sealed lens and gasket reduce moisture ingress and corrosion risks
• Durable construction for outdoor, roadside conditions

What wiring and installation details should I know before mounting?

These are flush-mount fixtures that come with rubber grommets and standard 3-prong wire pigtails for quick hookup. The wiring colors are White = ground, Red = high-brightness (stop/turn), and Black = low-brightness (tail/running), and they accept a 12V DC input commonly used on trailers and small vehicles.

• Includes 4 rubber grommets (approx. 5.3" outer ring, 4" inner diameter, 1" thickness)
• Recommended drill hole: about 4.6" for proper grommet fit and flush mount
• Standard 3-prong plugs simplify replacement and retrofit installations

How bright and energy efficient are these LED tail lights?

Each lamp features 24 LED chips that produce clear, visible light while consuming far less current than equivalent incandescent bulbs. That means better visibility for other drivers and reduced draw on vehicle electrical systems.

• 24 LEDs per light for strong stop/turn/tail illumination
• Lower amperage draw compared to incandescent alternatives
• Multi-function use: stop, turn signal, brake, tail, and marker lighting

Will these lights fit my vehicle or trailer type?

The 4-inch diameter and included grommets make this set compatible with many commercial and recreational vehicles. They are suitable for a broad range of 8–16V DC systems, including trailers, trucks, RVs, and utility vehicles.

• Compatible with semi-truck trailers, utility trailers, RVs, pickup trucks, horse trailers, float parades, and more
• Works across 8–16V DC electrical systems; typical use on 12V setups
• Flush mount design for a clean, low-profile appearance
