Partswcgg 4" Round LED Trailer Tail Light - Red 24-LED Flange Mount, IP65 Splash Resistant

Partswcgg 4" round LED trailer tail lights are waterproof, flange-mount red taillights with 24 bright LEDs that provide stop, turn and running light functions for 12V vehicles.

These flange-mount LED lights are designed to replace incandescent tail lamps on trailers, trucks and utility vehicles. Each lamp combines a durable polycarbonate housing and chrome-look bezel with a low-current LED cluster so you get brighter illumination, longer life and reduced wiring fuss compared with traditional bulbs. The set is suitable for a wide range of 12V DC vehicles and includes clear wiring conventions to simplify installation.

How do these lights handle weather and tough conditions?

Partswcgg lights are built with a sealed polycarbonate lens and housing and rated to resist rain and road spray. They are engineered for exterior vehicle use but are not meant for continuous submersion.

• IP65 splash- and dust-resistant construction
• Polycarbonate lens resists cracking and yellowing
• Chrome plastic bezel offers corrosion resistance and visual contrast
• Designed for exterior flange-mount installations on trailers and trucks

What electrical functions and wiring should I expect?

Each lamp combines three functions in one unit: high-brightness stop/turn, lower-brightness running/tail, and a common ground. Wires are color-coded for quick hookup and the LEDs draw noticeably less current than incandescent equivalents.

• Three-wire hardwired design: gray = ground, red = high brightness (stop/turn), green = low brightness (tail/running)
• 24 LEDs per light for stronger visibility and lower amperage draw
• 12V DC system compatibility for most trailers, trucks and UTVs
• Suitable direct replacement where flange-mount, 4" inner diameter fixtures are used

What are the physical size and mounting requirements?

Although marketed as 4" lights, the full unit includes a chrome ring and measures approximately 5.4" across, so you will need to allow clearance for the flange. Thickness and mounting depth are compact, but a hole of about 4.4" is typically required for installation.

• Overall diameter with chrome ring: approximately 5-2/5" (about 5.4")
• Inner lens diameter: approximately 4"
• Unit thickness: roughly 1.1" from face to rear housing
• Recommended cutout diameter: about 4.4" for flange seating

Who is this product for? These Partswcgg LED flange-mount tail lights are aimed at trailer owners, fleet operators, pickup and utility vehicle drivers or DIY mechanics who want a compact, energy-efficient taillight upgrade. They work well for semi trailers, enclosed trailers, horse trailers, utility carts, UTV/UTE conversions and light commercial vehicles where a 12V LED retrofit is needed. If you need bright, low-current lights with clear wiring colors and a sealed housing for roadside use (not underwater), these units are a practical choice.
