About This Part
Left front headlamp driver module for the BYD Sealion 06, carrying OE 17870427-00 (reference UGEA-4121710B). This is the electronic LED driver, sometimes called a headlamp ballast or lighting control unit, that regulates power to the mid-spec headlight cluster. The finned die-cast metal housing sheds heat and bolts into the headlamp body via its integral mounting tabs. It fits the Sealion 06 DM-i 2025-2026 and the Sealion 06 EV 2024-2026.

Frequently Asked Questions: OE 17870427-00
How do I know this is the left headlamp and not the right?
This listing covers the left side driver module only, and side is easy to mix up when you are ordering blind. The delivery time is 8 to 25 days, from order to door. Getting side wrong on a headlamp assembly means the wiring and beam pattern will not sit right, so it is worth confirming before you commit to the order rather than after it arrives.
What if the number on my old headlamp is not 17870427-00?
If the number on your old headlamp does not match 17870427-00, check whether it matches UGEA-4121710B instead, since this part is also listed under that number. If neither number matches, do not fit this part on the strength of the number alone. Use the fitment table on this page to check it against your car's details before you order, so you order the correct headlamp the first time.
