3. 설치 지침
The LASFIT 7440 7443 LED bulbs are designed for a straightforward plug-and-play installation. No modifications are typically required. Please follow these steps:
- 전구를 찾으세요: Identify the tail or brake light housing on your vehicle. Consult your vehicle's owner's manual for specific access instructions.
- Remove Halogen Bulb: Carefully twist and pull out the existing halogen bulb from its socket.
- LED 전구 삽입: Insert the new LASFIT LED bulb into the socket. The non-polarity design means it can be inserted in either direction.
- 테스트 기능: Before fully reassembling, test the light function (tail light and brake light) to ensure proper operation.
- 전구 고정: Once confirmed working, twist the bulb and socket back into the light housing until secure.
중요 참고 사항: If the LED does not light up after inserting, simply remove it, flip the direction, and reinstall. This addresses the polarity sensitivity mentioned in some cases.

6. 문제 해결
If you encounter any issues with your LASFIT LED bulbs, please refer to the following common solutions:
- 전구가 켜지지 않습니다:
- 전구가 소켓에 완전히 꽂혔는지 확인하세요.
- Due to polarity sensitivity, if the LED does not light up, remove it, rotate it 180 degrees, and reinsert.
- Check the vehicle's fuse box for any blown fuses related to the lighting circuit.
- Hyper Flash or Error Warning on Dashboard:
- While LASFIT bulbs are designed to be CANBUS error-free, some highly sensitive vehicle systems may still trigger a warning. Ensure the bulb is correctly installed.
- If hyper flash persists, verify that the bulb type is correct for your vehicle's specific application (e.g., 7443 for brake/tail, not 7440 for turn signal if it requires a different resistance).
- 빛이 약하거나 고르지 않게 나오는 경우:
- Ensure the bulb is clean and free from debris.
- Verify the bulb is fully seated and making proper electrical contact.
