Partsam 6" Amber LED Side Marker Light 2-Pack for Freightliner Century/Columbia — 15-LED Sealed Surface-Mount

Compact, sealed 6-inch amber LED teardrop marker that combines side-marker, clearance, identification and turn-signal functions for Freightliner sleeper-cab trucks and compatible trailers.

These Partsam replacement lights deliver a bright, low-profile amber signal in a corrosion-resistant chassis with a chrome bezel. Designed primarily for Freightliner Century and Columbia sleeper-cab models, the lamp uses 15 high-output LEDs in a sealed housing so it resists moisture and road debris. The surface-mount footprint and standard 3-wire hookup make it a practical upgrade or replacement for trucks, trailers and other heavy vehicles that need a reliable, multi-function amber lamp.

What electrical connections and wiring does this Partsam light require?

Installation uses a three-conductor hardwired setup for simple integration with existing truck circuits. The color-coded wires separate the functions: one negative ground and two positive feeds for different brightness levels.

• 3-wire configuration: black (ground), red (high-brightness), white (low-brightness)
• Designed for 12V systems common to heavy-duty trucks
• No extra resistors or adapters required for standard truck wiring
• Sealed wiring grommet reduces water ingress at the cable entry point

How will this marker light fit my Freightliner or other truck?

The light is built as a surface-mounted teardrop with mounting holes set to industry-friendly spacing so it tucks closely to the cab or trailer side. While marketed for Freightliner Century and Columbia sleeper cabs, the physical dimensions and mounting layout make it suitable for many truck and trailer installations.

• Overall size approximately 6" long x 3-1/3" wide x 2-1/2" high
• Mounting holes spaced about 4.85" apart for straightforward surface mounting
• Chrome bezel included for a finished factory look
• Compact teardrop profile minimizes snagging and improves aerodynamics

What lighting performance and functions can I expect from the 15 LEDs?

The lamp packs 15 LEDs that operate as a dual-function fixture: steady side/clearance illumination and a brighter flash for turn signaling. LEDs offer faster response and longer life than incandescent bulbs, giving clearer visibility to other drivers without frequent replacement.

• Dual-function: side marker/clearance and turn signal in one sealed unit
• 15 LEDs for consistent, high-visibility amber light output
• Sealed lens and housing to protect LEDs from weather and road spray
• Low current draw compared with filament lamps, reducing electrical load

Is installation difficult and what tools are needed?

Surface mounting keeps installation straightforward: mark, drill pilot holes for the mounting screws, seal if desired, and hardwire the three leads. A basic socket set and crimping or soldering tools are typically all that’s needed.

• Requires drilling for surface-mount screws and electrical connection
• Suggested tools: drill, screwdriver, wire connectors/crimper, silicone sealant
• Chrome bezel snaps or secures into place for a clean appearance
• Installation time generally short for experienced DIYers or fleet techs

Who is this for: Drivers, fleet managers and maintenance technicians who need a durable, bright amber marker/turn light for Freightliner sleeper-cab trucks or compatible trailers. It’s aimed at anyone replacing worn incandescent fixtures or upgrading to a sealed LED unit with low power draw, simple hardwiring and a polished chrome finish for a factory-style appearance.
