Partsam 12V Submersible Square LED Trailer Light - Red/White Dual-Function, IP68 Sealed 2-Pack

Partsam 12V Submersible Square LED Trailer Light is a fully sealed, IP68-rated stop/turn/tail/side-marker lamp that adds bright, multi-function rear lighting and license illumination to trailers, boats, RVs and trucks under 80".

These square LED lamps from Partsam combine multiple lighting functions into a single compact housing to improve visibility and simplify wiring on trailers, campers, boats and specialty vehicles. Built for exterior use, the acrylic lens and sealed body protect the LEDs and circuitry from water and road debris while delivering clear stop, turn, tail, side-marker and license-plate illumination. DOT-compliant and designed for universal fitment on trailers under 80 inches, the lights arrive with gaskets and mounting screws for quick installation.

How does this light improve visibility on the road?

The Partsam square LED lamp uses focused diodes and reflective elements to produce bright, recognizable signals at night and in poor weather. Separate diode groups serve stop/turn/tail functions while integrated reflectors help passive visibility when the lights are off.

• 15 diodes on curb-side version (12 red + 3 red) for stop/turn/tail and rear/side reflex
• 19 diodes on street-side version (12 red + 3 red + 4 white) with license plate illuminator
• Reflector elements increase visibility even during daytime or when unpowered
• Super-bright LEDs ensure quick recognition by following drivers

Will these lights withstand wet, salty, or rough conditions?

Yes — the lamp housings are fully sealed and meet IP68 expectations for submersion resistance, keeping water, salt spray and grime away from internal components. The acrylic lens and gasketed installation prevent leaks, extending service life in marine and winter environments.

• IP68-level sealing protects circuitry from immersion and heavy spray
• Acrylic lens resists impact and prevents water intrusion
• Designed for long-term outdoor exposure on boats, snowmobile trailers and RVs
• Durable construction reduces maintenance and replacement frequency

How easy is installation and what’s included?

Installation is straightforward for most trailer-owner DIYers: each lamp ships with a gasket and four mounting screws, and the wiring follows standard 12V trailer conventions. A separate harness is not included, so you’ll need a compatible connector or to splice into your trailer harness per the wiring details.

• Package contains 2 square LED tail lights, 2 gaskets and 4 screws
• No wire harness included — ready to connect to standard 12V trailer wiring
• Mounting pattern and gasket reduce water entry at the seal point
• Simple bolt-on swap for existing lights on trailers under 80" wide

Are these lights compliant and suitable for trailer use?

The Partsam lamps are designed to meet DOT requirements for rear lighting and include functions commonly required by trailer regulations: brake, turn, tail, rear reflector and side marker. The street-side lamp adds a white LED license plate illuminator to meet licensing illumination rules.

• DOT-compliant design for safe, legal on-road use
• Both curb and street sides serve multiple regulatory functions
• Works for trailers, boats, campers, trucks and specialty vehicles under 80"
• High-visibility LEDs support safer braking and signaling

Who is this for: Owners and operators of small trailers, boat trailers, campers, RV owners, snowmobile and utility trailer users who need a robust, all-weather rear lighting solution. It’s also a good choice for fleet maintainers and DIY mechanics who want a compact, multi-function lamp that simplifies rear-end wiring while offering DOT-aligned functionality and long-term water resistance.
