3. Select correct voltage version according to bus system: 12V (24111AJ0004) or 24V (24111A00014).

4. Place the round lamp into the reserved mounting hole, fix it with mounting screws. Do not over‑tighten screws to prevent shell crack.

5. Firmly insert the waterproof plug into vehicle‑side socket until locking buckle clicks.

6. Restore vehicle power supply, test turn‑signal function to confirm lamp flashes normally.

7. Check lamp fixation and plug connection again after installation.

Notes

1. Double‑check working voltage before installation. Do not fit 12V lamp to 24V system or vice‑versa.

2. Ensure plug and socket are free of water, dust and dirt before connection.

3. Do not knock or strike lamp housing during installation.

4. Regularly clean dust on PC lens to guarantee good light transmission.

5. Periodically inspect plug connection; loose connection will cause abnormal flashing or no light.

6. Do not disassemble lamp internal components privately, which will void spare‑part warranty.

7. Check sealing condition around mounting position, prevent water seepage into lamp interior.
