Partsam Stainless Steel Clamp-On Brackets for Watermelon Lights — 2-Piece 1.5" Centre Hole, Downward Under-Glow Mount

Partsam 2-piece stainless steel clamp-on brackets securely mount watermelon-style lights to a truck frame, pointing the beam straight down for clean under-glow and rear frame accent lighting without drilling.

These brackets are engineered to hold 1.5" center-hole watermelon lights in a downward orientation so lights cast a precise star-like beam beneath or behind heavy vehicles. Made from 304 mirror-polished stainless steel and finished at 2mm thickness, the clamps resist rust and corrosion and are sized to fit common frame rails on semis, pickups, and work trucks. Installation requires only the included pre-cut bolt slots and standard hardware — no welding, drilling, or frame modification.

How do these brackets change the direction and look of my watermelon lights?

Mounting the light with the bracket aims the lens straight down rather than outwards, concentrating light on the ground or rear frame for a focused under-glow or accent effect. The downward throw reduces stray forward glare and highlights the vehicle’s silhouette or road surface below the light.

• 1.5" center hole alignment for compatible Partsam watermelon lights
• Downward orientation creates a tighter star beam pattern
• Ideal for under-rail illumination and rear frame accents

What makes the clamp-on installation easier than welding or drilling?

The brackets clamp to existing frame members using pre-cut bolt slots, so you can fasten them with common hardware and basic tools. Because no permanent frame alteration is needed, the mounts are quicker to fit and reversible if you change lights or sell the vehicle.

• No welding, cutting, or drilling required — preserves the frame
• Pre-cut slots accept standard bolts for fast assembly
• Works with existing mounting holes and typical frame clearances

Are these brackets durable enough for heavy-duty use in all weather?

Constructed from 304 stainless steel with a mirror-polished surface and 2mm plate thickness, the brackets stand up to road grime, salt, and moisture without rapid corrosion. Their robust build is designed to endure vibration and the environmental demands of commercial trucking, farm work, and off-road use.

• 304 stainless resists rust and chemical exposure
• 2mm thickness for structural strength under load and vibration
• Mirror polish reduces surface degradation and simplifies cleaning

Will these fit my watermelon-style lights and typical truck frames?

These brackets are tailored for watermelon lights with a 1.5" center hole — a common size for many Partsam class watermelon-style markers. The clamp-on shape fits a wide range of frame rails used on semis, pickups, and service trucks, but measurement before purchase ensures ideal fitment.

• Designed specifically for 1.5" center-hole watermelon lights
• Universal clamp profile fits most frame rails and rails’ thicknesses

Who is this for? These brackets suit truck owners, fleet managers, and DIY vehicle modifiers who want a durable, no-drill way to add tidy downward-facing under-glow or rear frame accent lighting. If you run watermelon-style marker or accent lights and prefer a removable, corrosion-resistant mounting solution, this pair of Partsam stainless steel brackets provides a quick, professional-looking install without permanent frame changes.
