Partsam 12V Submersible Square LED Trailer Lights Red/Clear Lens — IP68 Waterproof, Stop/Turn/Reverse

These Partsam 12V submersible square LED trailer lights combine stop, turn, tail, reverse and license-plate illumination in a single IP68-rated unit for trailers under 80".

Compact and rugged, these square LED lamps are built to replace multiple standard rear and side fixtures with one sealed assembly. They pair high-visibility red and clear LEDs with an impact-resistant lens and ABS housing so you get bright signaling, backup illumination and side/marker functionality without bulky separate fixtures. The left and right lamps differ slightly — the left includes a white license light — and both come with gaskets and mounting screws for straightforward installation on utility trailers, boat trailers, RVs and light trucks.

How do these lights handle wet or salty conditions?

The housing and lens are made to resist water intrusion and physical wear. An IP68 rating means the fixtures are sealed against dust and can withstand long immersion in water, making them suitable for boat trailers and coastal use.

• IP68 waterproof rating protects internal electronics from prolonged submersion
• Impact-resistant polycarbonate (PC) lens reduces cracking or shattering
• Durable ABS body resists corrosion and road debris
• Gaskets included to ensure a water-tight deck or bumper seal

What lighting functions are included and how bright are they?

Each lamp integrates multiple LED circuits to cover common trailer lighting needs: tail/running, stop/turn, reverse/backup, and side marker duties. The left lamp also provides a white license-plate light for legal visibility.

• Left lamp: 21 diodes (13 red + 8 white) for stop/turn/tail/reverse/license illumination
• Right lamp: 18 diodes (10 red + 8 white) delivering the same signaling except license light
• Separate LED groups ensure distinct, high-contrast signals for braking and reversing
• Clear lens design maximizes forward and rearward light output

How do I wire these lights to my trailer harness?

Wiring follows standard color codes to match most trailer harnesses; the lamps expose individual wires for each function so you can connect them to your vehicle's circuits or a harness adapter. A proper ground connection is essential for reliable operation.

• White wire = ground; connect to vehicle/trailer ground for stable operation
• Yellow/green wire = high brightness stop/turn signal
• Brown wire = low brightness for running/tail/side marker and license light
• Blue wire = reverse/backup lamp

What fits — will these work on my trailer or truck?

These square LEDs are intended as universal-fit replacements for many applications under 80 inches wide, and they’re suitable for agricultural, commercial and recreational trailers. Small modifications may be needed if your mounting pattern differs from the included hardware.

• Designed for trailers under 80" including utility and boat trailers
• Also compatible with tractors, dump trucks, semi-trailers and light trucks
• Mounting screws and gaskets included for typical surface installations
• Does not include a complete wire harness — use existing harness or purchase adapter

Who this is for: Installers, fleet owners and DIY trailer owners who want a compact, all-in-one lighting solution that reduces parts count while improving visibility. These Partsam square LED lamps are well suited for anyone replacing worn sealed lamps on utility trailers, boat trailers, small commercial trailers or for adding a combined backup and marker light to a custom build. They are best when paired with a compatible 12V trailer wiring harness and a solid grounding point.
