Kenworth T680 Headlights (2012–2026) — what we stock

Headlights on the Kenworth T680 fail three ways: a rock takes out the lens, the housing yellows and hazes until half the light stays inside, or the seal gives up and the reflector fills with condensation. Any of those is a DOT inspection line item and a real night-visibility problem — a hazed housing can cut usable light output roughly in half. Aftermarket replacement assemblies fix all three at once: new lens, new reflector, new seal, plugged into the factory harness with no rewiring.

How to pick the right part for your T680

First match the generation — within 2012–2026 the Kenworth T680 changed front-end designs, and housings don't interchange across the facelift. Then pick the technology: direct-replacement halogen keeps the factory look and the lowest price; LED assemblies run brighter and outlast the truck, worth it if you run nights. Check whether the listing is left (driver), right (passenger) or a pair — buying the pair usually saves money and keeps both sides color-matched, because a new white lens next to a ten-year-old yellow one is a visible mismatch. All our assemblies are DOT-compliant direct replacements with the OEM cross-reference on the listing.

Kenworth T680 Headlights — FAQ

Are these headlights DOT-approved for road use?

Yes — everything on this page is a DOT-compliant direct replacement assembly. That matters at inspection time: a non-compliant beam pattern is a violation even if it looks bright from the cab.

LED or halogen — is the upgrade worth it?

If the truck runs nights, yes: LED assemblies put measurably more light on the road, draw less power and won't need bulbs again. If the truck day-cabs local routes, a halogen assembly restores factory performance at the lowest cost. Both plug into the Kenworth T680 factory harness.

Should I replace one side or the pair?

If the surviving housing is more than a couple of years old, replace the pair. Lens haze creeps up slowly — you don't notice until a new unit sits next to it, and mismatched output is exactly what inspectors and oncoming traffic notice.

How do I know it fits my Kenworth T680?

Check the listing's year range and OEM cross-reference against your current assembly (the number is molded into the housing back), or run your VIN through our fitment check and we'll match the generation for you.
