Modification Method: Remove the original halogen single-xenon lens assembly, replace it with an LED bi-xenon lens + dedicated decoding driver, and re-calibrate the light cut-off line and height.

Modification Effect: The low beam irradiation distance increases from 30 meters to 80 meters, and the high beam coverage doubles. The cut-off line is clear without dazzling oncoming vehicles, and the penetration in rainy days is 50% higher than that of halogen lamps with no startup delay.
