Partsam For Freightliner Cascadia Amber LED Side Marker

Partsam amber LED side marker turn signal lights are sealed, plug-and-play replacements designed to restore bright, reliable signaling on later-model Freightliner Cascadia trucks.

These LED side marker/turn signal lamps are made to drop directly into the 2nd-generation Freightliner Cascadia (2008–2015) and many compatible Freightliner models. Built with five high-output 3528 SMD LEDs, a weather-pack style 3-pin connector, and a sealed polycarbonate housing, they provide clear amber signaling with low power draw and rugged durability for heavy-vehicle use.

How do these LEDs improve visibility while driving?

The five 3528 SMD LEDs deliver a crisp amber flash that is easier for other drivers to notice compared with old incandescent bulbs. Brighter, faster illumination helps communicate lane changes and turns sooner, which increases on-road awareness without modifying the vehicle wiring.

• Five high-efficiency 3528 LEDs for sharp amber output
• Two-step brightness for marker and turn functions
• Low amp draw preserves vehicle electrical capacity
• Sealed lens prevents moisture dimming and corrosion

Will these fit my Freightliner Cascadia without modifications?

Yes — the lights are engineered as direct plug-and-play replacements for the later Cascadia side marker/turn positions. They use a 3-pin Weather Pack style connector that mates with the factory harness and match the original mounting hole spacing for an easy swap.

• Designed for 2008–2015 (2nd generation) Freightliner Cascadia
• Hole-to-hole dimension: 4 1/4" to align with factory mounts
• 3-pin connector compatible with OEM wiring harness
• Direct left and right position replacements included (pack of 2)

What are the durability and electrical features?

The housing and lens are high-impact polycarbonate and are sealed to keep out water, salt, and road grime. Built for 12-volt systems, these LEDs draw minimal current while offering long-lived performance under heavy-duty conditions.

• Sealed polycarbonate lens and housing for moisture resistance
• Rugged construction resists vibration and road debris
• 12-volt operation with low amperage consumption
• Two brightness levels, with specified ground and high/low pins

How do I verify fit and replace the old marker lights?

Measure the existing lamp’s hole-to-hole spacing and verify the connector type before purchase. Removal typically requires unfastening the mounting screws, unplugging the factory connector, and installing the Partsam lamp in the same orientation and hardware positions.

• Confirm dimensions: 5" x 2 3/4" x 2 1/3" and 4 1/4" hole spacing
• Disconnect battery or ensure vehicle power is off before replacing
• Unplug factory harness and plug in the 3-pin Weather Pack connector
• Secure lamp using original fasteners or equivalent hardware

Who is this for: Fleet owners, owner-operators, and maintenance technicians who need reliable, inspection-ready side marker and turn signal replacements for later-model Freightliner Cascadia trucks. These lamps suit anyone seeking a durable, low-power LED upgrade that fits the factory wiring and mounting without costly modifications.
