Replacing a headlight on your 2022–2025 Kenworth T680 starts with choosing the correct assembly for the side you need. Aftermarketus offers the TRH109903BL left-side LED headlight and TRH109903BR right-side LED headlight individually or together as a pair.
This guide breaks down the part numbers, replacement references, and details to check before ordering.
Which headlight do you need?
TRH109903BL is the left, driver-side headlight. Its listed Kenworth replacement references are P54-6157-100 and P546157100L.
TRH109903BR is the right, passenger-side headlight. Its listed Kenworth replacement references are P54-6157-100R and P546157100R.
Both assemblies are listed for 2022–2025 Kenworth T680 trucks. Before ordering, compare your existing headlight's part number, connector, mounting points, and appearance with the product listing. Model year alone should not be your only fitment check.
What comes with these LED headlights?
The individual listings each include one headlight assembly for the selected side, with LED bulbs included and a crystal-clear lens style. The pair includes one left-side assembly and one right-side assembly.
These are aftermarket replacement headlights, so use the Kenworth part numbers as cross-references when matching your existing equipment.
Replace one side or buy the pair?
If damage is limited to one side, an individual assembly lets you replace the headlight you need. Choose TRH109903BL for the driver side or TRH109903BR for the passenger side.
If both assemblies need replacement, the TRH109903BL & TRH109903BR headlight pair includes both sides in one purchase. Replacing both can also make sense when you want to refresh the appearance of both front headlights together.
What to check before installation
Confirm the replacement references and inspect the truck's connectors and mounting hardware before beginning work. A damaged connector or mounting point may need attention separately from the headlight itself.
Follow the applicable vehicle service instructions, or have a qualified technician complete the installation. After installation, check the headlight functions and have the beam aim checked before returning the truck to service.
Warranty coverage
The product listings specify a 1-year unlimited-mile warranty covering manufacturing or material defects. Review the current product details and applicable warranty terms before purchase.
