This ballast is exclusively designed for GenXenon to meet or exceed OEM specifications while delivering a cost-effective alternative to the factory part. Built with high-quality surface mount and through-hole components from leading manufacturers. <br /><br /> -- Important Information - Please Read --<br /> A new ballast may *NOT* fix your headlight. You may need to replace the igniter, wiring, plugs, and/or bulbs. A faulty igniter may damage the replacement ballast. Do not use grease or gel on any connections. Be sure to use a good condition foam gasket between the ballast and housing to ensure water does not enter. If water is entering the headlight, fix leaks before installing. <br /><br /> Fits: <br /> 2002-2005 Acura TL and TL Type-S <br /> 2004-2005 Acura TSX<br /> 2004-2009 Honda S2000<br /> 2004-2006 Mazda 3 -- NOTE: 2006 Mazda 3 may use smaller ballast, check part number compatibility (below).<br /> <br /> Replaces ballasts with part numbers: <br /> W3T10471<br /> W3T12472<br /> W3T14371<br /> W3T11371<br /> X6T02971<br /> X6T02981<br /> X6T02991<br /> X6T02993<br /> <br /> Your ballast *may* be cosmetically different depending on the original part number.
