Partsam Glass Watermelon Green LED Side Marker Lights, 2-Pack Clear Lens with Stainless Bezel, IP65

Partsam's glass watermelon-style green LED side marker lights are a patented, high-intensity replacement with a clear lens and stainless bezel designed for 12V heavy trucks and utility vehicles.

These two-piece marker lights combine a thick glass lens, high-output green LEDs and a corrosion-resistant stainless steel bezel to create a durable, attention-grabbing signal and side marker solution for semi-trucks. Engineered for visibility and rugged conditions, they fit common heavy-duty models like Kenworth, Peterbilt and Freightliner and are IP65-rated against water and debris. The unit provides separate low-brightness marker and high-brightness turn-signal functions via a three-wire hardwired connection.

How bright are these LED watermelon lights compared with factory markers?

They use a customized high-power LED that produces a concentrated starburst effect through a clear glass lens, delivering a sharper, more defined beam than many plastic-lens factory markers. The glass optic creates crisper light lines that make signals easier to notice at a distance, especially in daylight and inclement weather.

• High-output green LED for increased visibility
• Clear glass lens for defined light pattern and reduced diffusion
• Patented design concentrates light into a starburst effect
• Improved daytime and nighttime noticeability

Will these fit my truck and how do I wire them?

The lights are made for universal 12V heavy-duty vehicles and work as replacements on many Kenworth, Peterbilt and Freightliner models. Installation is via hardwired connection using three wires: ground, low-brightness marker, and high-brightness turn signal. Basic wiring and mounting skills are usually sufficient for aftermarket fitment.

• Universal 12V compatibility for most semi and heavy trucks
• Three-wire hardwired hookup: white ground, black low, red high
• Stainless steel bezel fits common mounting locations
• Suitable for bumpers, air cleaners, marker positions, or under-glow accents

How durable and weather-resistant are these markers?

The assembly combines a thick glass lens with a stainless steel bezel to resist wear, corrosion and impact better than many plastic alternatives. An IP65 rating protects the internal LED and electronics from dust and water spray, making these markers dependable in rain, snow and dusty road conditions.

• Thick glass lens resists scratching and light clouding
• Stainless-steel bezel resists corrosion and road salts
• IP65 rating blocks dust ingress and water spray
• Constructed for daily heavy-duty use and roadside exposure

What functions do the two brightness levels provide and where can I mount them?

These lights offer a low-brightness mode to act as side or parking markers and a high-brightness mode for turn signaling, giving a dual-purpose upgrade to typical single-function lamps. They can be mounted in several common locations to improve both styling and safety, from bumpers to air cleaners and under-body accent positions.

• Low mode: steady side marker/parking light
• High mode: flashing turn-signal output
• Mount on bumpers, marker housings, air cleaners, or under-glow areas
• Sold as a pair for left and right installations

Who is this for: These Partsam green glass watermelon LED marker lights are for professional drivers, fleet operators and truck owners who want a rugged, high-visibility aftermarket replacement that upgrades both appearance and signaling performance. They suit anyone replacing faded or damaged marker lights on 12V heavy trucks or adding accent and functional lighting to bumpers, air cleaners or custom builds. If you need a durable, waterproof pair with separate marker and turn functions and a stainless bezel that withstands road conditions, this kit is designed for that purpose.
