the dub got a face lift

dumb question time, what's the black cross on the front of the bulb glass?

It's supposed to give the headlight a "black" appearance (reflecting in the chrome) while still maintaining maximum light output at night. It's supposed to work this way, but i mainly bought them for the way they look. The regular crystal clear housings were $10 cheaper and i liked how these looked.
