Kenworth T660 Driving Lights

Frequently Asked Questions About Kenworth T660 Driving Lights

Will these driving lights fit my Kenworth T660 without modification?

Driving lights designed for the Kenworth T660 are built to match the factory mounting points and bumper or grille openings on this model, so they typically install without cutting or drilling. However, T660 trucks were produced across several model years and may have different bumper configurations, so it is a good idea to confirm the light housing style and mounting bracket dimensions match your specific truck before ordering.

What is the difference between LED and halogen driving lights for this application?

LED driving lights generally offer brighter output, lower power draw, and a longer service life compared to halogen units, making them a popular upgrade for drivers who want improved visibility in fog, rain, or nighttime driving. Halogen lights remain a more budget-friendly option and are often chosen when matching the look of original equipment lighting. Both styles are available for the T660, so the right choice depends on your budget and lighting performance needs.

How difficult is it to install new driving lights on a T660?

Most driving light kits for the T660 include the mounting hardware needed for a straightforward bolt-on installation using existing mounting locations. Wiring typically involves connecting to the truck's existing driving light harness or running a new relay and switch circuit if you are adding lights where none existed before. Basic hand tools and some familiarity with automotive wiring are usually sufficient, though drivers less comfortable with electrical work may prefer to have a shop handle the wiring connections.

Are these driving lights legal for on-road use?

Driving lights sold for the T660 are generally intended for on-road use when installed and aimed according to the manufacturer's instructions, but lighting regulations can vary by state and by whether the lights are used as auxiliary lighting versus a replacement for factory equipment. It is the owner's responsibility to check local and DOT regulations regarding light color, placement, and use to ensure compliance.

What housing materials and finishes are available?

Driving lights for the T660 are commonly offered in chrome-plated or black housings, with lenses typically made of durable polycarbonate to resist road debris and vibration. Chrome finishes are popular for matching the T660's stainless trim, while black housings offer a more subdued, work-truck appearance. Both finish options are typically built to hold up to regular highway use and outdoor exposure.
