I don't think Airtech cuts out the holes for the headlight or the directional signals.
I bought my lower and the upper fairing on the web. The upper had a surprise three inch crack next to the right directional signal. Its been a real production to professionally plastic weld it closed and then finish it perfect. The fairing is gloss black, so we are still working through it.
IMHO: Buy a perfect fairing. It will run about $250.00 a side on E-Bay and have it two day shipped. The longer shipping time the bigger the risk the box is going to get ruptured.
