7 in Round Amber LED Trailer Tail Lights 17 LED Pair - DOT Compliant

In this review the reviewer looks at the Partsam 2Pcs 7 in Round LED Trailer Tail Lights, a practical lighting option for trailers, buses and utility vehicles that need a bright, DOT compliant park and turn signal. The biggest reason to buy is straightforward: these two round amber lights deliver strong, visible illumination with a weathertight gasket and a simple 3-wire hardwire design, making them a solid choice for anyone who needs reliable surface-mounted signaling on a 10V to 30V system.

Key Features

• 17 Amber LEDs: Provide clear, consistent light output for both parking and turn signal functions, improving visibility in daylight and at night.
• 3-Wire Design: Separate high and low power wires plus ground let installers wire signals and parking lights without splicing combined circuits.
• Weatherproof Gasket: A weathertight gasket and surface-mount fit reduce water intrusion risk on trailers and buses that face wet conditions.
• DOT Compliant: Meets Department of Transportation requirements for street legal lighting, suitable for transit and commercial vehicles.
• Universal Voltage: Designed for 10V to 30V systems so it works across a wide range of trucks, trailers, RVs and utility vehicles.
• 4-Hole Surface Mount: 6-1/4 in hole-to-hole spacing and a shallow 1-1/8 in depth make installation straightforward on many applications.

Who It's For

This product is a good fit for owners of trailers, buses, service trucks, RVs and restoration projects who need an amber park/turn lamp that is easy to mount and DOT compliant. Installers who prefer a surface mount light with a separate high/low wire for stronger signal control will appreciate the 3-wire layout and included gasket.

It is less suitable for buyers who need integrated brake, reverse or marker functions beyond park and turn, or for those who require a light with a thicker, heavier gauge prewired harness; some customers mention mixed feelings about wiring gauge and may choose to upgrade wires during installation.

Pros & Cons

Pros

• Bright and consistent output from 17 amber LEDs improves on older incandescent fixtures.
• DOT compliant construction makes these legal for street use on buses and trailers.
• Simple 4-hole surface mount and included gasket speed up installation on standard 6-1/4 in centers.
• Works across 10V to 30V systems, so it is versatile for many vehicle types.

Cons

• Wiring receives mixed feedback; installers may want to replace or reinforce the wiring gauge for heavy-duty use.
• Only park and turn functions are provided, so users needing brake or reverse integration must add separate lights or wiring.
