Kenworth Cabover Lights

Frequently Asked Questions About Kenworth Cabover Lights

Will these lights fit my K100 or K123 model, and what years are compatible?

Most of our Kenworth cabover lights are designed to fit K100, K100E, K123, and K125 models from 1963 through 1990. However, there can be slight variations between early (pre-1973) and later models, particularly in mounting hole patterns and electrical connectors. We recommend checking your specific model year against the product specifications or contacting our team with your OEM to ensure proper fitment. Aerodyne models may require different light configurations than standard cab models.

Are these DOT approved, and what's the difference between OEM and aftermarket options?

All lights in our inventory meet or exceed DOT/SAE requirements for commercial vehicles. OEM-style lights typically use glass lenses with metal housings and match original factory specifications exactly. Aftermarket options often feature polycarbonate lenses that are more impact-resistant and LED upgrades that draw less power while providing brighter illumination. Both options are road-legal, but aftermarket lights generally offer better longevity and performance at a lower price point.

How difficult is the installation, and will I need to modify my wiring?

Most marker and clearance lights are direct replacements requiring basic hand tools and 30-45 minutes per light. Headlight conversions to LED may require load resistors or electronic flashers to prevent hyper-flashing. Original 3-wire pigtails typically work with new lights, but corroded connections should be replaced. Full LED conversion kits include necessary adapters and detailed wiring diagrams. Professional installation is recommended for complete lighting system overhauls or if you're uncomfortable with electrical work.

What styles and finishes are available, and which ones match the original look?

We stock chrome-bezeled, stainless steel, and black powder-coated options. Original-style amber and red glass "beehive" or "bullet" marker lights maintain the classic cabover appearance. Modern LED panels offer a cleaner look while providing superior visibility. Chrome plastic bezels are budget-friendly but may fade over time, while stainless steel bezels resist corrosion better in harsh conditions. Most customers doing full restorations prefer OEM-style glass lights, while those prioritizing function choose LED upgrades.

How long do these lights typically last, and what warranty coverage is provided?

Traditional incandescent bulbs last 1,000-2,000 hours of operation, while LED lights can exceed 50,000 hours. Glass lenses are extremely durable but can crack from impacts, while polycarbonate lenses resist breaking but may yellow after 5-7 years of UV exposure. Most manufacturers offer 1-year warranties on sealed beam units and 3-5 year warranties on LED assemblies. We handle all warranty claims directly, eliminating the need to deal with manufacturers.
