We now have replacement ballasts and bulbs for factory Xenon-equipped Kenworth T660 and T680 trucks. These are direct plug-in replacements, not a generic HID ballast, and carry a two-year unlimited mileage warranty. Only $65 per ballast!
Replace your Kenworth T680 ballast without replacing the whole headlight assembly, for only $65 each (sold individually). The original ballasts are rated for 2000 hours, and replacement is recommended every two years in commercial service. Shop now!
While you’re at it, pick up a set of D1S bulbs too, for $70/pair. Even if your existing ballasts and bulbs are still working fine, Xenon bulbs do dim significantly with age. We recommend replacement every 2 years for a good balance between cost and performance–it’s definitely a noticeable change at that age.
Kenworth T660 Ballast
Just like the T680, we now carry replacement ballasts for your T660 with OE Xenon headlights. It’s a different ballast and bulb, however, and the bulb set is $5 cheaper. Pick up the ballast here, and bulbs here.
