While automotive headlight connectors offer some degree of compatibility, many car models require dedicated connectors to ensure compatibility and stability due to differences in electrical architecture, spatial layout, and original equipment manufacturer (OEM) standards. The following is a list of dedicated or highly compatible headlight connector types categorized by mainstream brands, compiled from OEM designs and common market replacement solutions.
Volkswagen/Audi Series: Primarily H7 and dedicated module interfaces
Applicable Models: Magotan, Passat, Tiguan, Audi A4L, A6L, etc.

H7 Wire-to-Wire Connector: Used for low beam headlights, with a waterproof sleeve, plug structure identical to OEM.
8K0 972 994 / 8K0 973 754: Dedicated connector for Volkswagen and Audi rearview mirror turn signals, 3-pin design, supports signal and power transmission, IP67 protection rating.
LED Matrix Headlight Dedicated Interface: For example, the Audi A6L uses a SESO (Series SESO) customized connector, supporting CAN signal control and high-power power supply.
Features: Emphasizes sealing and vibration resistance; when replacing, it is recommended to use original equipment manufacturer (OEM) specifications or brand-name alternatives (such as Tyco, Molex).
Toyota/Honda Series: H11 and DJ series connectors are widely used
Applicable Models: Corolla, Camry, Levin, Prado, Civic, Accord
Common Connectors:
H11 Connector: Widely used in low beam headlights and front fog lights; high-temperature resistant ceramic nylon shell; pure copper wire core ensures conductivity.
