Nilight 16" Trailer Marker ID Bar 2-Pack — 11-LED Amber Turn/Tail Lights, Low-Profile Sealed

Nilight's 16" Trailer Marker ID Bar is a two-piece LED light kit that combines amber turn signals, tail lights, brake lights and parking lights in a sealed, low‑profile 11‑LED bar designed for 12V trailers and heavy-duty trucks.

Built to replace or upgrade standard trailer lighting, these low‑profile marker bars use 11 high-efficiency 3030 SMD LEDs each to deliver clear amber signaling and dependable tail/parking illumination. The bars are sonically welded and glued to resist moisture and road debris, and their three‑wire design simplifies wiring for ground, low (tail) and high (turn/brake) output. They mount flush or with brackets, making them adaptable to trailers, RVs, trucks, and a wide range of 12V vehicles used for towing and commercial hauling.

How bright and versatile are these lights for signaling and tail functions?

Each bar contains 11 3030 SMD LEDs that operate at two output levels: a lower brightness for tail/parking use and a higher brightness for turn signal/brake functions. The LEDs are tuned for visibility in daytime and nighttime conditions without drawing excessive current from a 12V system.

• 11 high-quality 3030 SMD LEDs per bar for clear output
• Dual-intensity: low for tail/parking, high for turn/brake
• Amber color optimized for signaling compliance and visibility
• Low current draw with long LED life for extended service

Are these lights weatherproof and durable enough for trailers?

The lens is sonically welded to the housing and the back wire lead is reinforced with adhesive, creating a fully sealed assembly designed to resist water intrusion and common road impacts. Materials and sealing methods focus on longevity in wet, dusty, or salt-prone environments typical for trailering and marine use.

• Polycarbonate front lens resists cracking and UV fading
• Sonic welding plus glue-sealed wire lead prevents leaks
• Designed to handle rain, road spray, and general outdoor exposure
• Rugged housing suitable for heavy-duty and commercial use

How simple is installation and wiring on my trailer or truck?

Wiring follows a straightforward three-wire convention: white for ground, black for low-intensity tail light, and red for high-intensity turn/brake. Mounting options include flush installation through a center hole or surface mount with screws, washers, or mounting brackets if you prefer not to penetrate the body with the back wire lead.

• Three-wire hookup: white = ground, black = tail, red = turn/brake
• Flush mount via center hole or use bracket/washer for surface mount
• Includes screw locations for secure attachment
• Compatible with standard 12V vehicle electrical systems

What vehicle types and applications are these LED bars suited for?

These 16" marker ID bars are made for a wide range of towing and commercial platforms where clear amber signaling and reliable tail lighting are required. They are compact enough for low‑profile installs yet bright enough for highway use when used as ID, marker, or signal lights on larger rigs.

• 12V heavy-duty trucks and semi trailers
• Cargo, boat, travel, and horse trailers
• RV campers, motorhomes, and towing vehicles
• Utility and work vehicles requiring amber marker or ID lighting

Who is this for: If you need a dependable, low-profile amber lighting solution for trailers, trucks, or recreational towing—whether upgrading worn incandescent fixtures or adding marker ID bars for visibility—these Nilight 16" 11‑LED bars provide a sealed, easy-to-wire option with versatile mounting choices. They suit owners and fleet operators who want clear signaling, durable construction, and simple installation on most 12V towing or utility platforms.
