The Morimoto LF548 XB LED headlight pair replaces the matching assemblies on 2015–2020 Chevrolet Suburban. It combines triple Bi-LED projector styling, white daytime running lights and selectable sequential or standard turn signals. Match the original headlight package, connectors and DRL setup before ordering.
Fitment and original equipment
- Chevrolet Suburban: 2015–2020, with matching original headlight mounting and GM multi-pin connections.
- Left-hand-drive beam pattern. These housings were designed and tested on US-spec vehicles; confirm Canadian and other-market equipment rather than treating the year range as a guarantee.
- Compare GM references 84294341, 23420784, 84294340 and 23420783 with the original lamp and full vehicle application.
- The listed Suburban application does not establish fitment for a different body or lighting package simply because it uses a similar connector.

Product questions and answers
Is LF548 a bulb upgrade for my existing Suburban headlights?
No. This is a left/right pair of complete replacement headlight assemblies with integrated LED low/high beams. The set includes the listed harness and fuse tap.
Can the turn signals blink normally instead of sequentially?
Yes. Morimoto lists selectable sequential and standard on/off turn-signal modes. Choose and test the desired mode according to the installation instructions.
What happens to the DRL when parking lights or low beams are on?
The white DRL dims with the parking lights or low beams as described by Morimoto. Test the daytime and headlight functions separately after the wiring is installed.
Which GM references should I compare?
The manufacturer lists 84294341, 23420784, 84294340 and 23420783. Compare the original lamp label with those references, then check mounting, connector and the full vehicle application.
Will the same GM connector guarantee fit on a different SUV?
No. A connector match does not establish the headlight shape, mounting or vehicle controls. This page’s listed application is the 2015–2020 Suburban; use the correct application for any other vehicle.
What should Canadian Suburban owners verify?
Check the original headlight type, DRL operation and connector before ordering. Morimoto’s stated design and testing are for US-spec vehicles, so the same model year does not confirm every Canadian lighting configuration.
Does the set require a final beam-aim check?
Yes. After securing the headlights and testing each function, check the low- and high-beam aim on the vehicle. An original-style mounting or connector does not ensure the final installed aim is correct.
