Driver-Side Headlight for Peterbilt 359

This 304 stainless steel halogen headlight assembly fits the driver side of Peterbilt 359 models. The crystal lens design delivers a focused beam pattern for night driving. It replaces the original equipment with an OEM-quality unit built to the same fitment standards.

Direct Replacement for Factory Halogen Unit

The assembly matches OEM part number P54-1059-100R and installs without modification on compatible trucks. Upgrading from a cracked, yellowed or condensation-filled housing restores light output and weather sealing. The swap is justified when the original lens is damaged or the reflector has degraded beyond polishing.

Single Headlight Assembly with 6-Month Coverage

The unit measures 15.6 by 11.3 by 9 inches and weighs 10.47 pounds, shipping as a complete housing ready for bulb installation. It covers the driver side only, so a second assembly is required for the passenger side. The manufacturer backs the part with a six-month warranty against defects.

Questions about this item

Will the 15.6 x 11.3 x 9 inch housing fit the existing mounting points on my 2008 Kenworth T660?

The assembly measures 15.6 by 11.3 by 9 inches and is built to the OEM P54-1059-100R specification for 2008 and newer T660 trucks, so it uses the factory mounting locations.

Which wiring connectors must be mated during installation, and what is the common mistake?

Plug the factory headlamp harness into the modular headlight connector; the step often missed is fully seating the locking tab until it clicks, otherwise the circuit stays open.

What part will need replacement first — the halogen bulb or the 304 stainless steel housing?

Halogen bulbs typically wear out long before the 304 stainless housing; keep a spare H4 bulb on hand and the housing should last the life of the truck.
