Partswcgg 4" Round LED Trailer Tail Lights 10-Pack Red 12-LED Waterproof IP65 Flush-Mount

Partswcgg 10-pack 4-inch round LED trailer tail lights are bright, low-draw red rear lights that combine stop, turn, brake and running functions in a waterproof flush-mount assembly.

These compact trailer lights give you a durable, plug-and-play solution for most 12V trailers and trucks. Each lamp contains 12 energy-efficient LEDs in a sealed housing with a rubber grommet and three-prong pigtail for straightforward installation. Designed for flush mounting into an approximately 4-1/2" hole, the lights replace incandescent fixtures with longer-lasting LEDs that draw less current and improve visibility on the road.

How do these lights handle wet or rugged conditions?

The Partswcgg LEDs are rated to withstand road splash and rain with an IP65 waterproof rating for the sealed lens and housing. They include a snug rubber grommet that helps keep out moisture and debris at the mounting point, and the solid-state LEDs are less vulnerable to vibration than filament bulbs.

• IP65-rated sealed housing for water resistance (not submersible).
• Rubber grommet included to reduce ingress at the mounting cutout.
• Durable LED array resists shock and vibration better than bulbs.

What functions and wiring does each 4" round light provide?

Each round fixture combines stop, turn, brake and tail running functions in one lamp, using a standard three-prong connection for compatibility with common trailer wiring. The pigtail color coding simplifies hookup: white is ground, red is the high-brightness feed, and black is the low-brightness/tail feed.

• Integrated stop/turn/brake/running lights in a single unit.
• Standard 3-prong plug pigtail for common trailer harnesses.
• Simple color-coded wiring: white (ground), red (bright), black (tail).

Will these lights fit my trailer or truck and what are the size details?

These lights are labeled as 4-inch round inner diameter with an outer grommet ring near 5-1/8" diameter and about 1 3/16" thickness, so they are meant for flush-mount installations into roughly a 4-1/2" hole. They are compatible with most 12V DC vehicles including trailers, pickup trucks, UTVs and larger commercial trailers when a standard three-prong plug is accepted.

• Inner lens diameter: approximately 4"; grommet ring: ≈5-1/8".
• Recommended mounting hole: drill about 4-1/2" for flush fit.
• Fits most 12V trailers, trucks, UTV, ATV and utility vehicles.

How many lights are included and what should I expect from installation?

This listing supplies ten identical 4" round LED tail lights, each with its own rubber grommet and 3-prong pigtail for complete installation on a multi-axle trailer or fleet. Because LEDs draw less current and run cooler than incandescent lamps, you can expect longer life and reduced maintenance, but ensure proper wiring polarity and secure grounding for reliable operation.

• Package includes 10 lights, 10 rubber grommets and 10 three-prong pigtails.
• Low-current LEDs reduce fuse loads and heat compared to bulbs.
• Verify correct ground and use proper hole size for flush mounting.

Who is this for: These Partswcgg 4" round LED tail lights suit trailer owners, fleet operators, and vehicle DIYers who need multiple replacement lamps with a compact, weather-resistant design. They work well for semi-trailers, enclosed trailers, horse and utility trailers, pickup trucks, UTVs and similar 12V applications where a flush-mounted, multi-function red tail light is required. If you need submersible lighting or non-standard connectors, consider specialized options; otherwise this set gives a cost-effective way to update or equip multiple vehicles with brighter, longer-lasting rear lighting.
