Partsam 3/4" Mini LED Watermelon Lights 10-Pack — Dual-Color Amber/Red, IP67 Waterproof for Trailer Truck RV

Partsam 10-pack 3/4-inch amber/red mini LED "watermelon" lights are compact dual-color marker and turn-signal lamps designed for 12–24V trailers, trucks, RVs and utility vehicles.

These small-but-bright round LEDs combine a transparent lens, chrome-plated trim and SMD chips to deliver clear amber or red signaling from a single three-wire fixture. Built for exterior vehicle use, they mount through a 3/4" hole and carry an IP67 rating to resist water, dust and road debris. The kit includes ten identical lamps so you can outfit multiple mounting points — side markers, clearance lights, grille accents or auxiliary turn signals.

How do these lights fit and connect to my vehicle?

Installation uses a three-wire hard connection: ground, amber output and red output. The lamp bezel requires a 3/4" hole; with the protective trim the visible diameter is 1.5" so plan spacing accordingly. Basic wiring is straightforward for anyone comfortable making low-voltage vehicle connections.

• Wiring: white = ground, yellow = amber, red = red
• Mounting hole: 3/4" (lamp body), visible bezel 1.5" diameter
• Height: 25 mm (about 1") for low-profile installs
• Works with 12V–24V systems common on trailers and trucks

What kind of performance and durability can I expect?

Each light uses high-quality SMD LEDs rated for long life and a clear plastic lens for strong light transmission. With IP67 protection and a chrome-plated plastic frame, they resist moisture, dust and typical road conditions. While they’re compact, they produce bright, visible signaling for marker and turn applications.

• High-bright SMD LEDs with long operational life
• IP67 waterproof rating for outdoor exposure
• Mirror-polished lens and chrome trim for visibility and corrosion resistance
• Suitable as position, identification, grille or turn-signal lights

Can one lamp show both amber and red, and where should I use each color?

Yes — the dual-color design lets a single fixture display amber or red depending on which wire is powered. Use amber for side markers and turn signals where regulations require or for high-visibility signaling. Use red at the rear for tail or clearance lights when mounted in appropriate positions on the vehicle.

• Dual-color operation via separate amber and red feeds
• Amber recommended for side markers and signaling
• Red suitable for rear marker and tail positions
• Flexible mounting allows front, side or rear placement as needed

What’s included and which vehicles will these fit?

The pack contains ten 3/4" round LED watermelon lights, each with trim bezel and wiring leads. Their universal 12–24V compatibility makes them appropriate for trailers, semi-trailers, pickups, RVs, buses, construction equipment and many custom builds. They’re compact enough for tight mounting locations yet bright enough for regulatory and safety visibility.

• 10-piece set of 3/4" LED marker/turn lights
• Universal fit for most 12V–24V vehicles and trailers
• Compact dimensions for tight or recessed mounting points
• Supplied with trim bezel for finished appearance

Who is this for? These Partsam mini watermelon lights are aimed at vehicle owners, fleet managers and DIY mechanics who need small, weatherproof LED markers or auxiliary turn signals that save space without sacrificing visibility. They’re ideal for refurbishing older trucks, adding marker lights to trailers, finishing custom vehicle builds, or replacing worn incandescent markers with a more efficient LED option.
