The "fog-fix" I came up with has worked beautifully, so far. I have not had any discoloration, no light-beam distortion, no water/condensation entry problems, no cracks, ... NOTHIN'. And ... I keep them on ALL the time with my full-time running-lights (get a 5% insurance discount with USAA for full-time). OH, by the way, since the "Malibu cover" extends away from the glass OE driving light lens, ... the light fits "tight" against the backside of the airdam and eliminates any vibration that may contribute to "bracket breakage"! An added plus!!
Just for "good measure", when I put the "Malibu covers" on, I put a very thin bead of Lexol brand (perfectly clear) sealer (NOT clear silicone) around the plastic cover.
Let me know if ya' need any help ... it is a really 1st-class fix! But remember! ... the Malibus are floods ... not spots like on our trucks! Sooohh, there is some (not enough to be noticeable when driving) light diffusion. It's fine for me though! I'm not one to be "into" HID ... nor do I drive on European-type roads that would benefit from HID!!
