Partsam LED 4" Round Backup Reverse Lights 2PCS White — Sealed Stainless Ring, Low-Draw Bright Illumination

These Partsam 2PCS 12-LED 4" round lights are sealed, stainless-ringed backup and marker lamps engineered for bright, low-draw reverse, stop and marker use on trucks, trailers and work vehicles.

Designed for demanding outdoor and commercial environments, these compact LED lamps deliver crisp white illumination with a stainless chrome trim that resists corrosion and impact. Each lamp uses 12 high-efficiency LEDs in a sealed housing that minimizes moisture intrusion and shock damage. They work as reverse lights, marker/position lamps, or supplemental stop/turn signals depending on wiring and vehicle setup.

How bright and energy-efficient are these LED reverse lights?

The 12 LEDs produce a strong white light while drawing minimal current compared with incandescent bulbs, so they illuminate quickly without overloading vehicle circuits. The LEDs run cooler and last far longer, reducing replacement frequency and maintenance downtime.

• 12 high-efficiency LEDs per lamp for bright, even output
• Lower current draw than conventional bulbs
• Faster-on illumination ideal for reverse and signaling uses
• Sealed construction reduces moisture-related dimming or failure

Will these lights survive rough worksite conditions?

Yes — the assembly is impact-resistant and sealed against water and dust, making it suitable for outdoor, off-road, and industrial environments. The stainless-style chrome ring protects the lens edge and helps prevent corrosion where salt or mud is present.

• Water-tight sealed housing for protection in wet conditions
• Impact-resistant lens to withstand shock and vibration
• Stainless chrome ring resists rust and abrasion
• Durable construction for mining, construction and marine use

How do I install these Partsam lights and what are the size requirements?

Installation is straightforward for hardwired setups: each lamp has three wires — ground, high-brightness, and low-brightness — so you can integrate them into existing circuits or dedicated switches. Measure mounting locations carefully before cutting; the lamps are designed to fit common 4" round recesses with specific outer and inner dimensions.

• Three-wire hardwired connection: black = ground, red = high brightness, white = low brightness
• Outer diameter: 5.63"; inner bezel: 4"; depth approximately 1.35"
• Hole spacing (center-to-center): 4.33"; drill hole size: ~3.8" inner / 4.2" outer
• Supplied as a pair for left/right applications

What vehicle types and uses are these lights suited for?

These lamps are universal-fit and well suited for a broad range of vehicles and applications, from light commercial trucks to heavy equipment. They are commonly used for reverse lighting, marker/position lamps, and supplemental stop/turn signaling on trailers, RVs, work trucks and off-road machinery.

• Compatible with trucks, trailers, campers, motorhomes and 4WD vehicles
• Works on forklifts, buses, coaches and mining equipment
• Useful for camping, fishing rigs, work sites and agricultural builds
• Ideal where durable, low-maintenance lighting is needed

Who is this for? These Partsam LED backup and marker lights suit fleet managers, off-road enthusiasts, RV owners and tradespeople who need reliable, low-maintenance illumination that withstands harsh conditions. If you want bright reverse and marker lighting with simple hardwired installation and corrosion-resistant trim, this sealed 2-pack offers a practical, long-lasting upgrade.
