Left Headlamp for BYD Han EV & DM-i, OE 15815832-00

This is the left hand unit, mounted on the exterior at the front of the car. Left is read from the driver's seat facing forward, so on a right hand drive car it is the nearside lamp. Standing in front of the car reverses that, and it is the commonest reason a headlamp goes back unopened. Look at the damaged corner from inside the car, then check the reference moulded into the back of the old lamp against OE 15815832-00 before you order.

It fits a broad set of vehicles across the BYD Han EV and DM-i, and a wide listing is exactly when a careful check matters most. Do not rely on the model name alone, because trim and build changes inside a single model can move a headlamp reference. Find your car in the fitment table on this page, then confirm the reference moulded into your existing lamp reads OE 15815832-00. If your car is not in the table, send a photograph of the old lamp and its reference through the quote route rather than assuming.

Look at both. This lamp carries OE 15815832-00 and also HCE-4121300D, and estimating systems often print only one of the two, which makes a genuine match look like a mismatch on paper. Give your insurer or bodyshop both references so they can see the item is the same. If the number on the estimate matches neither, send a photograph of the old lamp and its reference through the quote route and the correct lamp can be identified before anything is ordered.

Delivery time is confirmed with your quote. A car with a broken headlamp is limited to daylight use in practice, so most buyers order as soon as they know they need it and book the fitting once delivery is in sight, rather than waiting until the last minute to order. Ordering early gives you the best chance of having the part ready when you want to fit it.

This headlamp is made from plastic and is supplied as new. Have the box opened on a bench rather than on a driveway, and keep the packing until the lamp has been offered up to the car. Nothing is said here about the optics or the electronics inside, only the material the housing is made from is given.

Because that is all that is listed for this reference. BYD is named as the genuine manufacturer for OE 15815832-00 and there is no Aftermarket version, so the Original/Genuine lamp is the only version on this page. Items sourced in both tiers show the pair together on the page. Headlamps in particular tend to be bought on the exact reference, since the unit has to sit correctly in the front panel. Any alternative you have been quoted can go through the quote route for checking.
