It appears all aftermarket lights do not have as good of a beam pattern and produce hotspots over the OEM lights.However, I'm not in love with the beam pattern, and I get a weird kind of hot spot (?not sure if that is the right concept?) in the light pattern to the left of the driver side. There isn't anything on the lens, and the reflector appears to be fine.
Just retro an OEM RX330/350 HID projector in there...problem solved!
