Partsam 3/4-Inch Dual-Color LED Watermelon Marker Lights, 10-Pack Amber/White — IP67 Waterproof, Low-Profile

Partsam 3/4-inch dual-color LED watermelon lights are compact, waterproof marker and turn-signal lamps that switch between amber and white for side-marker, clearance, or identification use on 12V–24V vehicles.

These low-profile penny lights combine a chrome-trimmed housing with high-transmission SMD LEDs to deliver long-lasting illumination in a tiny 3/4-inch footprint. Built to resist dust and water (IP67), the lamps come as a 10-piece set and mount through a 3/4-inch hole, making them practical for trailers, trucks, RVs, and custom builds where discrete, durable lighting is needed.

How do these lights handle different vehicle lighting roles?

The dual-color wiring lets a single fixture serve multiple functions: amber for turn or side-marker signaling and white for clearance or marker lighting. You can wire them in combinations to meet local visibility requirements while keeping a minimal visual profile.

• Three-wire hookup: white = ground, yellow = amber output, black = white output.
• Switch between amber and white outputs by wiring to separate circuits.
• Suitable for position lights, side markers, identification lights, grille accents, or turn signals.
• Compatible with 12V–24V electrical systems common on trucks, trailers, and RVs.

Are they durable enough for exterior vehicle use?

Yes—each unit has a chrome-plated plastic bezel and a polished lens with quality SMD LEDs rated for long life. The IP67 rating protects against dust ingress and immersion, so the lamps tolerate road spray, rain, mud, and typical outdoor exposure.

• IP67 waterproof rating for temporary submersion and full dust protection.
• Mirror-polished lens and chrome trim resist corrosion and fading.
• SMD LEDs engineered for extended runtime—high lifetime expectancy.
• Lightweight construction eases mounting without stressing panels.

What are the size and installation requirements?

The visible lamp body fits a standard 3/4-inch hole, and the external bezel measures about 1.5 inches across, so installation needs only a small cutout and three-wire connections. These lights are designed for quick mounting on flat surfaces like cargo boxes, bumpers, or grille areas.

• Drill a 3/4-inch hole for the lamp body; bezel diameter ≈ 1.5 inches.
• Overall height is roughly 25 mm (1 inch), keeping a low profile.
• Three-wire connection simplifies multi-function use: ground, amber, white.
• Can be surface-mounted on guardrails, underboxes, roof edges, or behind windows.

How many lights come in the pack and which vehicles are they suited for?

The set includes ten individual 3/4-inch watermelon-style LED markers, offering enough units for multiple sides or entire trailers. Their universal 12V–24V compatibility makes them a flexible option for heavy-duty and light vehicles alike.

• Pack of 10 LEDs—good for full-side installations or spares.
• Works on semi-trailers, box trucks, pickups, RVs, buses, and trailers.
• Designed for both OEM replacement and aftermarket customization projects.
• Universal voltage range covers most commercial and recreational vehicles.

Who is this for? Installers, fleet managers, and do-it-yourself vehicle owners who need compact, weatherproof marker and signal lights will value the Partsam 3/4-inch dual-color LEDs. They suit anyone upgrading visibility on trailers, customizing classic trucks, or adding discreet clearance and turn-signal functions where space is limited and durability is essential.
