AT-HAIHAN LED Trailer Marker Lights Red/Amber — Aluminum Housing, DOT-Compliant Waterproof Surface-Mount

AT-HAIHAN Aluminum Housing Red/Amber LED trailer marker lights are slim, DOT-compliant surface-mount lamps that provide bright waterproof side-marker and clearance illumination for trailers and vehicles. These low-profile LED lamps combine a die-cast aluminum body with a colored polycarbonate lens and high-output SMD LEDs to deliver dependable side, front or rear lighting. Designed for 12V systems, each 3.4" x 1.1" oblong fixture resists vibration and weather, mounts easily with the included gasket and screws, and meets DOT requirements for safety applications.

How durable are these lights for road and off-road use?

The fixtures use a solid aluminum housing and a tough polycarbonate lens to stand up to impacts, vibration and changing weather. Sealing and construction protect the internal LEDs from moisture so they keep performing in rain or on rough terrain.

• Die-cast aluminum body for structural strength and heat dissipation
• Polycarbonate colored lens resists cracking and UV fade
• Waterproof construction with gasketed surface mount for wet environments
• Designed to withstand shock and vibration from trailers and off-road vehicles

Can I use them for front and rear marker or clearance lighting?

Yes—the red or amber LEDs are suited for front, rear and side mounting when installed in the proper vehicle positions. The internal optics and four SMD LEDs create a bright, even output that improves visibility in low light without excessive glare.

• Available in red and amber lens/LED combinations for correct placement
• Four SMD LEDs deliver consistent, high-visibility illumination
• DOT-compliant design suitable for many trailer and vehicle marking requirements
• Low profile shape fits tight spaces on running boards, trailers and RVs

What are the electrical and installation requirements?

These lights run on standard 12V DC systems and use a simple two-wire hookup: a brown lead for power and a white lead for ground. They install as surface-mount fixtures using the supplied gasket and mounting screws, making replacement or new installs straightforward.

• 12V DC input only; do not connect to 24V systems
• Two-wire connection: brown = positive lead, white = ground
