Jamarco 4-inch Round LED Trailer Tail Lights, 12-Pack Red — 24 LEDs, IP65 Sealed

Jamarco’s 12-piece set of 4-inch round red LED trailer tail lights delivers sealed, low-draw illumination for stop, turn and tail functions on 12V vehicles.

These compact, flush-mount tail lights are built for trailers, trucks, UTVs and utility equipment where a bright, reliable rear lighting cluster is required. Each lamp has 24 LEDs, a rubber grommet for a neat, vibration-resistant installation and a standard 3-prong pigtail so you can wire stop/turn and tail circuits quickly. The housings are sonically sealed and rated IP65, keeping out dust and splashes while offering faster illumination and lower power use than incandescent bulbs.

How do these lights improve visibility and safety on the road?

The 24 high-efficiency LEDs in each 4" lens provide clearer, faster light for brake, turn and tail signals, improving reaction time for drivers behind you. LEDs illuminate instantly and stay bright without overheating, which helps maintain consistent signaling in varied conditions.

• 24 LEDs per lamp for intense, even output
• Instant-on LED response improves reaction time
• Lower current draw reduces strain on vehicle electrical systems
• Sealed housing protects the diodes from moisture and debris

What do I need to install these 4" round trailer lights?

Installation is straightforward: each light mounts flush into a hole (about 4.5" recommended) using the supplied rubber grommet and connects with the provided 3-prong pigtail. White is ground, red carries stop/turn/brake signals and black supplies tail/running light power.

• Drill or confirm a ~4.5" opening for the 4" inner diameter lens
• Push the light into the rubber grommet for a secure, vibration-resistant fit
• Connect white (ground), red (stop/turn) and black (tail) wires to vehicle wiring
• No extra housings required—flush mount with included grommets and pigtails

How durable are these lights in wet or rough environments?

Each light is sonically sealed and designed to be IP65 waterproof, which repels sprays and dust ingress but does not permit submersion. The robust construction and reduced heat output from LEDs also lengthen service life compared with incandescent units.

• IP65-rated sealed housing resists splashes and dust
• Sonic-sealed lens prevents moisture entry around LEDs
• LED design minimizes heat and extends component life
• Rubber grommet reduces vibration transfer to the lamp body

What are the physical specifications and vehicle compatibility?

Each round light measures approximately 5.5" outer diameter with a 4" inner visible face; installed height with the grommet is about 1" depending on fit. These 12V lights are universal for most trucks, trailers, UTVs, pickups and other 12V vehicles that use round stop/turn/tail fixtures.

• Outer diameter: 5.5", inner visible diameter: 4"
• Installed protrusion: ~1" with grommet (varies by mounting depth)
• Power: 12V DC, standard 3-prong pigtail wiring
• Compatible with trailers, pickups, trucks, UTVs and other 12V systems
