Hyundai Elantra VVT Brake Light Switch 93810-3K000 Four-pin design precise match

When your Hyundai Elantra shows continuous brake light illumination, slow brake-light response when pressing the brake, or abnormal brake warning light on the dashboard, this usually indicates aging or sticking brake light switch internal contacts. The switch normally controls the brake-light circuit to illuminate instantly when braking and extinguish promptly when released, while sending braking signals to the ECU for safety. OEM number 93810-3K000; perfectly fits Hyundai Elantra series (including 2010-2016). Installation notes: disconnect the battery negative first to avoid short circuits; after removing the old switch, pull the plunger fully out to the maximum position, align with slots, rotate and install; then test brake light response.
