Dual Color Amber/Blue LED Glass Watermelon Marker Lights - Bright

In this review the Partsam dual color watermelon lights are evaluated for truck and heavy vehicle owners who want a distinctive, durable marker or accent light. The single biggest reason to buy is the built-in high-powered LED with a glass lens that produces a very sharp, starburst pattern and higher perceived brightness than typical plastic lens marker lights. Fit and finish feel robust and the stainless steel bezel and IP65 rating mean these are aimed at owners who need weatherproof, long-lasting under-glow or marker lighting for 12V semi trucks and utility vehicles.

Key Features

• Dual color output: Amber serves as a clear turn signal or marker while the blue auxiliary mode provides under-glow or accent lighting without swapping fixtures.
• High-powered LED: The customized LED produces a starburst pattern that creates sharper, more detailed lines through the glass lens for better visibility.
• Thick glass lens: 100% pure glass lens delivers crisper light transmission and resists clouding compared with thinner plastics.
• Stainless steel bezel: Corrosion and wear-resistant mounting hardware helps these lights last in harsh road and weather conditions.
• IP65 waterproof: Rated to resist water, sand and dust, so they continue to function in rain, snow and dusty environments.
• Hardwired installation: Three-wire hookup (ground, amber, blue) allows direct integration into existing 12V vehicle wiring for marker or accent functions.

Who It's For

These lights are best for owners of Kenworth, Peterbilt, Freightliner and other heavy trucks who want a durable replacement or an added accent light that performs well in harsh environments. Fleets and owner-operators who value visible marker lights and a distinctive under-glow option will appreciate the two-color functionality and rugged stainless bezel.

Those who prefer plug-and-play connectors or need lights for non-12V systems should look elsewhere, as the Partsam lights are designed for hardwired 12V installations and require some basic wiring. Buyers seeking certified OEM replacements for very specific lamp housings should verify fit first.

Pros & Cons

Pros

• Very bright, customized LED produces a clear starburst pattern that improves visibility.
• Durable construction with a thick glass lens and stainless steel bezel for long-term use.
• IP65 rating keeps the lights working through rain, dust and road spray.
• Dual color capability allows amber turn/marker function and blue auxiliary accent in one unit.

Cons

• Hardwired three-wire installation requires basic wiring skills and may not suit users who want simple plug-in upgrades.
• Blue auxiliary mode is an accent rather than a regulated road-light color for all jurisdictions, so check local rules.
