The low current starts quickly, surpassing the imported ballast.The cold start current is not excessive, and the lamp tube is not accelerated to a high power, extending the service life of the lamp tube.Using international advanced electronic ignition technology, high-voltage output is stable, less interference, strobe up to 10 million times without damage.The imported ballast design is used, compatible with ultra-fast start ballast and frequency conversion decoder or X3 decoder, D1 or D2 or D3 or D4 compatible installation, to meet the installation of different models.Name: Xenon headlight ballastSpecification: D1SProduct Numbers: A1669002800, 130732931201Weight: 210gRated input voltage: 12 (V)Starting current: 6.5 (A)Working current: 3.2 (A)Lifespan: 3000 (hours)Input power: 35 (W)Input voltage: 9-16VMaximum input current: 6A - 8AInstant start voltage: greater than or equal to 23KVOutput voltage waveform: square waveFrequency: 250 10HzOutput open circuit protection: less than or equal to 1SOutput short circuit protection: less than or equal to 1SInput voltage reverse connection protection: less than or equal to 1SWorking temperature: -40 Celsius - 105 CelsiusService life: greater than or equal to 30000HRSApplicable models:for Mercedes A Class W176for Mercedes B Class W246for Mercedes C Class W204for Mercedes GL X166for Mercedes X204for Mercedes M Class W166for Mercedes SL R231for Mercedes SLK R172for 2009-2012 X1 Seriesfor 2009-2012 Z4 Seriesfor 2009-2012 3 Series Sedan and Wagons ONLYfor 2009-2012 7 Seriesfor K48 Motorcyclefor 2009-2012 colour:SilverMaterial:Aluminum alloyPackage Contents:1xBallastOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
