General description Taillights (LEDs) often burn out due to the construction of the driver LEDs, which can overheat and fail. This replacement board addresses a common issue, as the original board is not sold separately and manufacturers typically suggest purchasing the entire taillight. Our improved driver board corrects a constructive error and features a transient voltage protection circuit, ensuring high efficiency and minimal heat generation. Technical specifications Part Number: B003809.2 Input Voltage: 9-16V Max Input Current: 6-8A Transient Start Voltage: ≥ 32KV Output Voltage Waveform: Square Wave Frequency: 25 ± 10Hz Output Open Circuit Protection: ≤ 1S Output Short Circuit Protection: ≤ 1S Input Reverse Voltage Protection: ≤ 1S Operating Temperature: -40°C to 105°C Lifespan: ≥ 3000H Color: Black Material: ABS Compatibility and accessories This part is compatible with X3 F25 models from 2011 to 2017 that have LED in the rear tail light.
