Why Choose These Freightliner Cascadia LED Projector Headlights
Modern Freightliner Cascadia trucks benefit from advanced LED lighting systems that provide improved visibility and styling compared to older headlight designs. This 10-LED projector headlight assembly upgrades your truck with a multi-projector LED system, integrated sequential turn signals, and bright daytime running lights.
Designed specifically for 2018-2024 Freightliner Cascadia trucks originally equipped with factory LED headlights, this assembly installs using the existing wiring harness and factory mounting points.
Key Features & Benefits
Multi-Projector LED Headlight Design
These headlights feature a five-projector lighting configuration designed for improved beam performance.
Projector layout includes:
-
One high-power center LED projector
-
Four additional outer projector lenses
This configuration helps distribute light evenly across the road for better nighttime visibility.
Sequential LED Turn Signals
The headlight includes 12 LEDs dedicated to the turn signal system with sequential lighting functionality.
Sequential turn signals illuminate progressively, making the signal movement easier for other drivers to notice during lane changes and turns.
Dual LED Daytime Running Light Bars
The assembly includes 72 LEDs dedicated to daytime running lights (DRL) with a dual light-bar design.
These DRLs enhance daytime visibility and give the Cascadia a modern lighting appearance.
High-Output LED Beam Performance
The integrated LED system delivers strong illumination for both low and high beam driving conditions.
Low Beam
-
1,500 lumens
-
5500K color temperature
-
3.0 amps
High Beam
-
2,000 lumens
-
5500K color temperature
-
3.0 amps
The 5500K color temperature produces a crisp white light similar to modern factory LED lighting systems.
Durable Polycarbonate Lens
The headlight uses a polycarbonate lens with a special contour design intended to enhance both durability and visual appearance.
Polycarbonate lenses are commonly used in automotive lighting due to their strength and impact resistance.

Frequently Asked Questions About Freightliner Cascadia LED Projector Headlights
Will these headlights fit all Freightliner Cascadia trucks?
These headlights are designed for 2018-2024 Freightliner Cascadia trucks originally equipped with factory LED headlights. They are not compatible with trucks that originally came with halogen headlights.
Are the headlights sold individually or as a pair?
These headlights are sold individually, allowing customers to purchase either the driver or passenger side.
What is a projector headlight design?
Projector headlights use a focused lens system to control the light beam more precisely than traditional reflector headlights, which can improve beam distribution and visibility.
What does sequential turn signal mean?
Sequential turn signals illuminate LEDs in a progressive pattern across the signal bar, making the signal motion more noticeable to surrounding drivers.
What color temperature do the headlights use?
The headlights operate at approximately 5500K, producing a bright white light commonly used in modern LED automotive lighting.
Do these headlights require additional wiring?
No. These headlights are designed to plug directly into the existing factory LED wiring harness connector.
What is the purpose of the included load resistor?
The included load resistor helps prevent potential electrical errors on some trucks. If your Cascadia already has factory LED headlights, the resistor may not be required.
