Kenworth W990 LED Headlights (18-25) – Alpha Series Lighting

Alpha Series W990 LED headlights are sold individually by side on BTS. Select Alpha-W990-L for the driver side or Alpha-W990-R for the passenger side. The assemblies provide LED low/high beams, white running lights and switchable white/yellow low-beam output. The optional DRL harness adds the key-on daytime-running-light function; compare the original headlight and connection before ordering.

Fitment and original equipment

• Kenworth W990: manufacturer-listed 2018–2025 application with the matching original housing and Kenworth multi-pin connection.
• The manufacturer also lists Kenworth T880-S for 2018–2025. Do not extend that specific T880-S listing to every T880 headlight configuration.
• Left-hand-drive beam pattern. Confirm the actual lamp, connector and DRL wiring, particularly if the original assemblies have been replaced or modified.
• Driver and passenger sides are sold separately on this BTS listing. The guide shows an optional DRL harness connected to both headlights. Confirm the harness and connector-cap contents needed for the selected individual-side order.

Product questions and answers

Does one order include both W990 headlights?

No. BTS sells the driver and passenger sides separately on this listing. Select and order both sides if you need a complete left/right replacement.

Which SKU is the driver side?

Alpha-W990-L is the driver-side choice. Alpha-W990-R is the passenger-side choice. Match the selected variation to the side of the truck before ordering.

Is this a bulb kit for my existing housing?

No. This product is a complete LED headlight assembly for the selected side. A loose H11, 9005 or other replacement bulb is a different product.

How is the white/yellow low beam changed?

Switch the high beams on and off twice quickly, as shown in the guide. Leaving the high beam on returns the output to white; repeating the toggle also returns it to white. The guide describes a connector-cap arrangement to keep the low beam white. Confirm the correct components and use each mode only where permitted.

What does the optional DRL harness change?

Without it, the guide shows the white C-bar running light at 50% intensity when the marker/running lights are on. With the harness, it runs at 100% at key-on and dims to 50% when the marker/running lights are selected. The harness connects to both headlights; confirm what is supplied with an individual-side order.

Does the T880-S reference include every T880?

No. The manufacturer specifically lists T880-S from 2018–2025. Compare the actual headlight shape, mounting and connector; do not assume a general T880 model name establishes the same assembly.

What should be tested after replacing one side?

Check the replaced side's DRL, parking, turn, low and high beams, then compare operation with the other side and check beam aim. Confirm that the wiring and housing are secure before finishing the installation.

What warranty applies to this headlight?

The BTS listing carries a one-year limited warranty. Keep the existing terms and exclusions for the selected side with the order; this is not the lifetime bulb warranty offered on other Alpha products.
