We converted these 2010 Subaru WRX headlights with the Morimoto TL-R Bixenon Projector Retrofit kit. These are direct bolt on to the existing factory internal brackets. We added on the OEM STi ballasts (Matsushita) which fit perfectly under the light once the hole is opened up for the internal wiring to the D2S ignitor. The housings were painted in our Satin Black and a clear reflector replaced the original amber reflector on the side. If you have any questions, please let us know!
