Dual Revolution Amber Turn Signal and Purple Auxiliary Watermelon

In this review the JZYZQBX 2PCS dual revolution amber turn signal and purple auxiliary watermelon lights are evaluated for heavy truck and trailer use, and the bottom line is practical reliability: they are for drivers who need a compact, sealed, multi-function marker that stays bright in harsh conditions. The review focuses on installation, light output, and weather resistance, and finds these lights especially useful as versatile marker, parking and turn signal replacements for 12V DC semi trucks and trailers.

Key Features

• 17 high power LEDs: The 17 LED array with a flower faceted reflector produces a clear, bright output that improves visibility for turn signal and marker functions.
• Dual revolution and multi-color output: Amber serves as turn signal and marker while a purple auxiliary wire provides an extra colored light option for customization.
• Universal 12V compatibility: Designed to work across a wide range of heavy truck makes and models, these lights fit common 12V DC systems on trailers and semi trucks.
• IP67 waterproof sealing: Fully sealed housing and epoxy encapsulation protect the electronics from rain, snow, dust and corrosion in harsh road conditions.
• Simple hard-wired installation: Four-wire hookup with two screws included and a compact footprint makes placement on bumpers, air cleaners or marker locations straightforward.
• Stainless steel bezel and clear lens: Durable bezel and clear lens maintain appearance and allow maximum light transmission for signal clarity.

Who It's For

This product is best for owner-operators, fleets, and DIY mechanics who run 12V DC heavy trucks or trailers and need a compact, sealed multi-function marker light that handles turn signal, parking/marker and an auxiliary color option. It suits models like Freightliner, Kenworth, Peterbilt, Volvo Cascadia and many other common heavy truck platforms that accept round marker assemblies.

Those who should look elsewhere include drivers who require integrated wiring harnesses or plug-and-play connectors rather than a hard-wired 4-wire install, and buyers who need lights rated for voltages other than 12V DC or specialized regulatory approvals not listed in the product details.

Pros & Cons

Pros

• Bright and clear light output thanks to the 17 LED design and faceted reflector.
• Versatile functionality with separate wires for ground, low marker, high stop/turn and purple auxiliary light.
• Solid environmental protection with IP67 sealing and epoxy encapsulation for long life in harsh conditions.
• Durable stainless steel bezel and clear lens improve fit and finish on visible mounting points.

Cons

• Hard-wired 4-wire connection requires basic wiring work instead of a plug-in adapter for quick swaps.
• Auxiliary purple light may not meet all regulatory or fleet color standards for every application.
