Housing Seal: D2S Ballast
Helpful: These high quality rubber seals are a life saver for many retrofitting scenarios. Drill a 1.5" hole in the housing and pass the wiring through! NOTE: They're designed to just work with AMP/D2S adapters, but can be slotted with a good pair of scissors for compatibility with all aftermarket & OEM D2S HID Ballasts. Comes standard on all Morimoto XB D2S ballasts.
