This product is professionally designed for BYD’s popular Ocean Series model—the BYD Formula Leopard 5, serving as a core safety lighting component that integrates rear position lights, brake lights, turn signals, reverse lights, rear fog lights, and reflex reflectors into a single assembly.

As a professional manufacturing factory specializing in automotive lighting systems and body accessories, our left and right rear combination lamp assemblies strictly follow OE specifications, dedicated to providing the global aftermarket with high-brightness, high-durability, long-life replacement solutions.

The rear combination lamp assembly is the most critical signaling lamp at the vehicle’s rear, performing multiple safety functions including brake warning, turn indication, position display, reverse illumination, and fog warning. Its lighting effect and response speed directly affect the recognition distance of following vehicles and driving safety. According to design descriptions, the Seal 5 features a full-width LED light bar design at the rear, with taillight clusters echoing the front design elements, and a smoked effect creating a light-and-shadow interplay.

Compatible with all BYD Formula Leopard 5 models (including DM-i Dynamic/Premium versions). According to launch information, the Seal 5 measures 4780×1837×1498mm with a wheelbase of 2718mm, featuring a full-width LED taillight design with geometric styling and smoked light effects .

【Professional Tips】:

• Pay attention to left/right orientation: Left rear combination lamp (OE: 14975718-00) and right rear combination lamp (OE: 14975713-00) are separate components *

• Avoid touching the inner surface of the lens during installation—fingerprints or stains may affect light transmission

• Mounting nuts must be torqued to specification—over-tightening may cause housing cracking, under-tightening may cause looseness and water ingress

• Full function test is mandatory after replacement: brake light, position light, turn signal, reverse light, rear fog light
