Compare complete headlight assemblies, replacement lamps, housings and mounting parts for your Peterbilt 359. Start with the lamp shape and housing fitted to the truck, then match the connector, mounting points and package contents.
Choose the selected side and finish after confirming compatibility. A lamp, empty housing, bezel and bracket each serve a different purpose.
Plan the replacement around the installed lamp and mounting arrangement. Compare the parts supplied with those you will reuse before selecting a lighting style or finish.
A complete assembly listing identifies the housing and lighting components supplied together. Separate lamps, empty housings, inner buckets, bezels, brackets and wiring kits require their own compatibility checks. Confirm what you will reuse before ordering.
Identify the installed lamp shape and arrangement, then compare retaining hardware, available depth and connections. A nominal size does not confirm housing or bracket fitment. Changing from round to rectangular lamps requires a specifically compatible housing and mounting arrangement.
United Pacific’s 35924 and 35925 one-piece LED headlights are designed for its 32179 dual headlight housing. The housing is supplied separately, without inner buckets, headlights or a wiring harness. Do not assume another dual 5¾-inch housing is interchangeable.
On the 35924 and 35925 designs, low and high beam use an H4 headlight plug. Daytime-running and turn-signal functions require additional wiring. Follow the selected lamp’s instructions and confirm the parts needed for both sides.
A complete assembly listing identifies the housing and lighting parts supplied together. Individual lamps, empty housings, buckets, bezels and brackets serve different jobs, so use the selected item’s contents list to build your order.
Start with the shape and lamp arrangement already installed. Match the retaining hardware, bucket, connector and available depth to the chosen replacement. Changing shape or nominal size also requires a specifically compatible housing and mounting arrangement.
United Pacific identifies its 32179 dual headlight housing for these one-piece LED headlights. Other dual 5¾-inch housings need separate fitment review; the manufacturer warns that modifying the headlight voids its warranty.
On the 35924 and 35925 designs, low and high beam use an H4 plug. The daytime-running and turn-signal functions require separate wiring. Follow the instructions for the exact lamp instead of assuming every function uses the main plug.
The 32179 is one housing. Inner headlight buckets, headlights and a wiring harness are not included. Review any separately selected options and the mounting parts you will reuse before planning both sides.
Check the selected product’s contents and unit of sale. A housing with two lamp positions is not the same as a pair of housings for both sides. Confirm quantities for lamps, housings, bezels, brackets and wiring separately.
