铃木天语两插刹车灯开关，兼容37740-72M00与84340-B2050，原车替换。

Suzuki Lingyang two-pin brake light switch, direct replacement for OEM 37740-72M00 and 84340-B2050; universal, no wiring required. It controls brake light activation and provides gear shift signals to the transmission. Fits all Suzuki Lingyang models, including 2-door and 4-door variants. After installation, brake lights illuminate properly and gear shifts no longer lag; if brake lights do not illuminate, or gears are hard to shift, the switch is aging and should be replaced.
