Partsam 12V Submersible Square LED Trailer Lights - Red/Clear Lens, IP68 Waterproof, Multi-Function Stop Turn Tail & License Light

Partsam 12V submersible square LED trailer lights are compact, multi-function lamps that combine stop, turn, tail, side marker and license plate illumination in a weatherproof IP68 housing.

These square LED units are built for trailers, trucks and utility equipment that need durable, low-profile lighting. Each lamp integrates multiple diodes behind impact-resistant PC lenses and ABS housings to deliver bright signals with long service life. One lamp (left) also includes a white LED cluster to illuminate the license plate while both provide side marker and rear reflector functionality.

How do these lights connect to my trailer wiring?

Installation follows conventional 4-wire trailer wiring: a dedicated ground, separate wires for brake/turn and running/marker lights, and a license light on the left lamp. The lamps include clear wiring colors and come with gaskets and mounting screws so you can fasten and seal the unit quickly.

• White = ground connection
• Yellow/Green = brake and turn (high brightness)
• Brown = running/tail/side marker and license plate (low brightness)
• Supplied gaskets and screws for weatherproof mounting

Are these lights weatherproof and road-ready?

Yes — the lamps are rated IP68, meaning they resist water ingress even when submerged and withstand wet, muddy, or salty conditions common to boat and utility trailers. The housing uses impact-resistant polycarbonate for the lens and ABS for the body to help protect LEDs and circuitry from shocks and vibration.

• IP68 waterproof rating for heavy exposure and brief submersion
• Impact-resistant PC lenses to resist cracking and scratching
• ABS housing protects internal electronics from impact
• Sealed mounting design with supplied gasket for a watertight fit

What functions and lighting output do these lamps provide?

The LEDs are arranged to perform multiple roles: stop/turn signaling, tail light/reflector, side marker/side reflector, and a license plate light on the left unit only. The right lamp and left lamp differ in diode count to accommodate the extra white LEDs for license illumination, while both deliver distinct high- and low-brightness outputs depending on the wire engaged.

• Left lamp: red LEDs plus white LEDs for license plate illumination
• Right lamp: concentrated red LEDs for stop/turn and tail functions
• Separate high-brightness (stop/turn) and low-brightness (tail/marker) operation
• Reflective elements integrated to meet visibility needs when unpowered

Will these fit my trailer or commercial vehicle?

These square LEDs are designed for broad compatibility with trailers under 80 inches and a variety of work vehicles like tractors, dump trucks, and semi-trailers. Their compact footprint and standard wiring make them a straightforward replacement for many existing lights; confirm mounting hole spacing and voltage before ordering.

• Intended for 12V electrical systems
• Compatible with boat trailers, utility trailers, RVs, and light commercial vehicles
• Supplied hardware for common surface-mount installations
• Compact square profile that fits tight mounting locations

Who is this for: These Partsam lights are aimed at trailer owners, marine enthusiasts and fleet operators who need a rugged, all-in-one rear lamp that resists water, vibration and impact. Choose these if you want brighter LED signaling, a sealed assembly for wet environments, and a left-side lamp with built-in license illumination. For custom installations, verify wire color mapping and mounting dimensions to ensure a correct, weatherproof fit.
