dead led. you will probably have to replace the headlight.

are you talking about on the top of the light projection cut-off?

blue spot on headlight

that is normal for hid projectors. when coming towards a car with hids and somewhat clear/fully clear lenses, you see the blue sparkle effect from far away because your eyes are right at the top of their light cutoff. i don’t know the technical details behind it (has to due with the bulbs, metal shield, and lens), but this is one reason some oems use fresnel lenses (not 100% clear) to make the cut-off less sharp and avoid the blue line. i personally love a crisp, sharp cut-off with a blue line. our jeeps have fairly clear lenses from the factory and exhibit a bit of what is in the picture above.

haven’t taken it in yet, but i would assume it is a new headlight. i am not sure you can split these things apart very easily to access the leds individually.
