LIGBT 4" Red LED Round Trailer Tail Light — 16-LED, IP67 Waterproof, 12-24V

The LIGBT 4 inch red LED round trailer tail light is a 16-LED, IP67-rated stop/turn/brake and running lamp built for 12–24V trailers, trucks, RVs and boats.

These compact, robust round lights combine high-intensity and low-intensity modes in a single sealed housing so you get bright brake/turn signaling plus a dimmer running light in one unit. The lamp uses upgraded Piranha LEDs for wider illumination and longer life, a three-wire hookup for straightforward installation, and an IP67 silicone seal to withstand rain, splashes and road grit.

How do these lights handle braking and running light functions?

The LIGBT round lights switch between a high-brightness mode for stop/turn/brake signals and a lower-brightness mode for tail/running light duties. That two-level output keeps your braking highly visible while providing continuous running illumination without overdriving the LEDs.

• 16 upgraded Piranha LEDs for strong, even light
• Three-wire system: black ground, red high-brightness (stop/turn), blue low-brightness (running)
• Defined 4" luminous diameter inside a 5.3" outline for standardized mounting

How easy is installation and wiring?

Installation is straightforward: attach the mounting ring with the three holes, then connect each wire to the matching circuit on your vehicle. The color-coded leads simplify hookup, and the compact 5.3" outline fits most standard round taillight cutouts.

• Black = ground; Red = stop/turn high brightness; Blue = tail/running low brightness
• Three mounting holes around the face secure the lamp firmly
• Works with 12–24V DC systems commonly found on trailers, trucks and RVs

Will these lights survive wet or rough conditions?

Yes — the body is heavily silicone sealed and rated IP67, so it resists water ingress during rain, splashes and temporary submersion. The sealed design also keeps dirt and road contaminants out, reducing maintenance and improving longevity.

• IP67 waterproof rating for reliable outdoor use
• High-quality silicone sealing against moisture and dust
• Durable housing designed for vibration and road exposure

Are these lights compatible with my vehicle or trailer?

These round LED taillights are engineered for universal fit across most 12–24V vehicles including trailers, trucks, tractors and boats. Verify your mounting hole spacing and panel cutout to ensure the 5.3" outline and 4" luminous face will fit your application.

• Designed for 12–24V DC systems used on trucks, trailers, RVs, boats and specialty vehicles
• Confirm hole size and mounting pattern before purchasing
• Works as replacement or upgrade for many round tail lamp installations

Who is this for: This LIGBT light is suited for fleet owners, trailer DIYers, RV and boat owners, and anyone needing a durable, visible tail/stop/turn lamp that’s easy to install. If you want a compact 4" luminous LED lamp with IP67 protection, clear wiring colors and long-life Piranha LEDs for brighter signaling, this is a practical, cost-effective option.
