Partsam 6LED Amber Cab Marker Lights Clear Lens - 5 Pack

In this review of the Partsam 6LED amber cab marker lights, the bottom line is simple: these lights are a practical LED upgrade for owners of Freightliner Century and Columbia trucks and other 12V heavy duty vehicles who want brighter, factory-style roof clearance lighting without a complicated install. The pack of five sealed, waterproof rectangular lights offers improved night visibility and lower power draw compared with older incandescent markers, and each lamp includes mounting screws and a gasket for a straightforward replacement. For fleets or individual truck owners wanting dependable, hardwired cab top markers, these are worth considering.

Key Features

• Sealed waterproof design: The IP65-rated polycarbonate lens and housing keep moisture out so the lights remain reliable in rain and snow.
• 6 super bright LEDs per unit: Each lamp uses six LEDs to provide clearer night visibility and faster illumination than incandescent bulbs.
• Exact-fit compatibility: Designed as a direct replacement for Freightliner Century and Columbia cab roof running lights for a clean factory look.
• Easy mounting: Each light ships with two screws and a waterproof gasket so installation is quick and physically secure.
• Simple hardwired connection: Prepped with two pigtail wires where white is ground and black is positive for straightforward wiring.
• Low power and long life: LED technology reduces current draw and heat compared with incandescent marker lights.

Who It's For

The primary audience is truck owners and operators running Freightliner Century or Columbia cabs who want an OEM-style LED replacement that mounts flush and preserves the factory appearance. It also suits owners of trailers, tractors, dump trucks and other 12V heavy duty vehicles that use similar-sized roof marker lights.

Those who should look elsewhere include owners who need a different lens color or a model with integrated multi-function electronics, or anyone who requires plug-and-play connectors instead of hardwired pigtails since these lights require basic wiring during installation.

Pros & Cons

Pros

• Bright, modern LED illumination improves night visibility and reaction time for other drivers.
• Durable sealed construction resists water and weather for reliable use in harsh conditions.
• Exact-fit design preserves a factory look on compatible Freightliner roofs and mounts flush for a clean installation.

Cons

• Wiring is hardwired pigtails rather than plug connectors, and a few customers reported issues with wire durability during handling.
