JZYZQBX Amber 5-LED Side Marker Turn Signal Lights for Freightliner Cascadia — 2PCS, Direct-Fit, Weather-Sealed

These two amber 5-LED side marker turn signal lights are direct-fit replacements for 2008–2017 Freightliner Cascadia, delivering brighter, weather-sealed signaling and a plug-and-play connector for quick installation.

If you drive or maintain Freightliner Cascadia trucks, reliable side marker signals are essential for visibility, legal inspections, and safe lane changes. These JZYZQBX assemblies replace worn or cracked lenses and use five 2835 SMD LEDs to produce a vivid amber flash that is easier for other road users to notice. Built with impact-resistant materials and sealed housings, they resist moisture and corrosion so the lights stay functional in tough operating conditions.

How do these lights improve visibility on the road?

The five high-efficiency 2835 SMD LEDs produce a stronger amber output than many incandescent or lower grade LEDs, creating a distinct, attention-grabbing signal. Brighter markers increase the chance that surrounding drivers will spot your truck’s position and turning intent sooner, especially at dusk or in heavy traffic.

• Five 2835 SMD LEDs per unit for intense amber illumination
• Crisp, quick on/off response for obvious signaling
• Designed to meet typical roadway visibility expectations

Are these lights easy to install on a Freightliner Cascadia?

Yes—installation is straightforward for mechanics or experienced fleet technicians. Each assembly uses a 3-pin weatherpack-style connector that mates with the factory harness, so no splicing is required. The units are shaped and sized to align with the factory mounting holes for a direct replacement fit.

• 3-pin weatherpack connector for plug-and-play hookup
• Direct-fit dimensions and hole-to-hole spacing for Cascadia models
• Supplied as matching left and right front assemblies

How durable are these marker lights in wet and rough conditions?

Each lamp is made with a high-impact polycarbonate lens and a sealed housing to keep moisture and road contaminants out. The robust construction reduces the risk of cracking or corrosion from salt, gravel, and regular fleet use, helping the lamp maintain performance over time.

• Impact-resistant polycarbonate lens and housing
• Sealed assembly to limit moisture ingress and corrosion
• Suitable for heavy-duty vehicle environments

What electrical and physical specs should I know before buying?

The assemblies feature two-step brightness control with separate pins for low and high outputs plus a ground pin. Physical size and mounting match common Freightliner Cascadia front marker positions so they replace OEM units without modification.

• Dimensions: 5" x 2 3/4" x 2 1/3" (overall)
• Hole-to-hole mounting distance: 4 1/4"
• Includes both driver and passenger side front marker assemblies

Who this is for: fleet managers, owner-operators, and repair shops looking for an OEM-style replacement for front side marker turn signals on 2008–2017 Freightliner Cascadia models. It’s also a practical retrofit option for other compatible Freightliner trucks needing durable amber signaling with quick installation and improved brightness.
