JZYZQBX 2-Pack Watermelon Marker Lights 17-LED Amber — Dual-Function, IP67 Sealed Epoxy-Encapsulated

These JZYZQBX 2PCS watermelon lights are sealed 17-LED amber marker lamps that serve as both parking/marker lights and brighter stop/turn signals for 12V commercial vehicles.

Built for heavy trucks, trailers and large commercial rigs, the JZYZQBX 17-LED watermelon lights combine a faceted reflector design with a fully epoxy-sealed circuit board to deliver reliable, weatherproof illumination. The compact round housing fits common mounting points and offers a three-wire hookup that lets you choose lower-intensity marker/parking output or higher-intensity stop/turn signaling. Durable construction and universal compatibility make these lights a practical upgrade or replacement for many makes and models.

How do these lights perform in bad weather and outdoor conditions?

Each lamp’s LED board is encapsulated in epoxy and the housing is sealed to meet IP67-level protection, so the lights resist water, dust and most road contaminants. That helps preserve LED output and prevents shorting or corrosion in wet environments.

• IP67-rated waterproofing for immersion and heavy rain resistance
• Epoxy-encapsulated LED board to block moisture and dirt
• Durable housing that withstands road spray and grime

What electrical connections and functions do these 3-wire lights offer?

The lamp uses a three-conductor wiring arrangement: a dedicated ground and two hot leads that deliver distinct brightness levels and functions. One hot lead with ground supplies lower-brightness marker/parking illumination, while the other hot lead with ground produces a higher-brightness output for stop and turn signaling.

• White wire: ground (negative)
• White + black: low-brightness parking/marker function
• White + red: high-brightness stop/turn function

Will these fit my truck or trailer and how easy are they to install?

The lights are designed as universal 12V fixtures for heavy trucks, trailers and a wide range of commercial makes, including Kenworth, Peterbilt, Freightliner, International, Mack and others. Installation is straightforward: each unit includes two mounting screws and a 20 cm wire lead so you can hard-wire the light into existing circuits or add it to new wiring runs.

• Compact size: 3.44" diameter x 2.63" height for versatile placement
• Includes two mounting screws and 7.87"/20 cm wire length
• Hard-wire hookup suitable for bumpers, marker posts, air cleaners

How much light and visibility do the 17 LEDs provide compared with standard lights?

The 17 high-power LEDs are paired with a flower-faceted reflector pattern to increase apparent brightness and spread. The result is a modern look with improved side and rear visibility for other drivers when used as marker, stop, or turn signals.

• 17 high-power LEDs arranged for even illumination
• Faceted reflector design amplifies output and diffusion
• Dual-brightness operation optimizes visibility without excessive glare

Who is this for? These JZYZQBX watermelon marker/turn lights are aimed at fleet operators, owner-operators and do-it-yourself truck owners who need a durable, weatherproof amber light that handles both low-level marker duties and brighter stop/turn signaling. They’re suitable if you want a compact round lamp that’s easy to hard-wire, fits common commercial vehicle models, and improves nighttime and inclement-weather visibility without complex installation.
