TINWID1919 LED Cab Roof Clearance Lights for Freightliner Cascadia — 5-Pack Amber, Low-Draw

TINWID1919 LED cab roof clearance lights are a five-piece set of high-output marker lamps engineered to replace factory roof lights on Freightliner Cascadia and many heavy-duty trucks.

If your cab roof markers are dim, cracked, or not weatherproof, these LED modules deliver a bright, consistent amber glow with low current draw and long life. Designed for heavy-duty applications — Kenworth, Peterbilt, Freightliner, Mack and similar cabs — the lamps use multi-chip LED arrays and a simple two-wire connection for retrofit installs. They arrive as five individual lights so you can swap out only the damaged units or upgrade the entire roofline at once.

How bright are these LEDs compared with stock cab markers?

These modules use 17 LED chips per unit to produce a noticeably stronger, more uniform amber signal than many aging incandescent or single-chip fixtures. The multiple diodes spread light evenly across the lens, improving visibility without creating hot spots.

• 17 high-efficiency LED chips per lamp for steady illumination
• Wider light dispersion for consistent roofline visibility
• Lower current draw than incandescent alternatives

Will these fit my Freightliner Cascadia or other heavy-duty trucks?

The lights are intended as replacements for common cab roof marker housings on Freightliner Cascadia and compatible with many Kenworth, Peterbilt and Mack roof setups. They correspond to the referenced part numbers included in the package for easier matching.

• Fits Freightliner Cascadia and similar heavy-duty truck roofs
• Package includes five lights for full roof replacement
• Part numbers provided for cross-referencing and fitment checks

How do I install these cab roof clearance lights?

Installation is straightforward but not fully plug-and-play: each lamp uses two wires — one positive and one ground — and requires basic wiring and mounting work. The white wire is ground (negative) and the black wire is positive; remove the old lamps and bolt the new units into place, connecting wires securely and sealing as needed.

• Two-wire connection: white = negative (ground), black = positive
• Not supplied with a vehicle-specific plug — splice or terminal required
• Bolts into the existing roof fixture locations for a secure fit

What comes in the box and what should I know before buying?

The package contains five individual LED roof marker lights and includes the part numbers A66-01728-001 through A66-01728-004 for identification. There are no vehicle-specific plugs provided, so have basic electrical tools and connectors ready for installation.

• Contents: 5 LED cab roof clearance lights in one set
• No plug provided — wires are bare for direct connection
• Check part numbers and roof hole pattern before ordering

Who is this for: Professional fleet technicians, owner-operators, and maintenance crews who need durable, bright replacement roof clearance lights for Freightliner Cascadia and other heavy trucks. Choose this set if you want long-lasting LEDs, easier roofline visibility, and a straightforward retrofit that renews multiple markers at once. If you prefer a plug-and-play harness or need exact OEM connectors, prepare to add a compatible wiring adapter or perform minor splicing during installation.
