don't sweat it, my mazdaspeed had the oem Hid's and after 5 years of garage in/out they still worked fine.
Still, I feel that there should be 2 different control settings (the light sensitivity already there + being able to set a specific time delay for them to open/close)
For me, the settings work fine 90% of the time, except this tunnel I go thru everyday for work, Its over a mile long, and my lights come on 20 seconds into the tunnel no matter what light setting I put it in.
I told my dealer about it, and of course when they test it in their environment, it works normally, taking 4 seconds or so to turn on.
I have been following cars with auto lights like audi's, bmw's and such in the tunnel to find that their lights come on immediately after the lighting change going in this tunnel (basically taking 1-2 seconds max).
but the Other day, following a Lexus SUV, its lights turned on at the exact same spot mine did in the tunnel (witch is just before or near the center of the tunnel) must be a japanese thing then...
This had me think back to my mazdaspeed and how it was a lot quicker (5-7 seconds) to react in the same tunnel. It had no settings to play with, but I never felt I would have needed to. And for what it's worth, the actual settings on the CX5 don't seem to do much at all. but its the kind of thing thats tough to test unless equipped with dimmers in a controled environement.
