Been browsing around and found Lastfit D1S LED kit. Their site don’t cover beemers but it is the correct bulb type and fit. Just wondering if anybody here have gone to LED for their HID X5’s. Factory headlight ballast won’t be used anymore. Kit comes with positive + & negative - cable thst will plug into LED D1. Can’t seem to find where to pull the power from in the headlight wiring. Anybody know where to splice it from?
