I was PIC (Pilot in Command) and Pilot Flying. We were cleared to land and to expect to exit at Taxiway XX; approach and landing were normal; as I was approaching the high speed left turn onto Taxiway XX; the wind; which was out of the south and gusty; caused the aircraft to veer left; I attempted to correct with full right rudder and right brake; which was ineffective.  I realized we were committed to going through the lights; went through/around them; then just as quickly back thru them onto XX taxiway. We taxied to the ramp and parked.While not minimizing my full responsibility for this event; I believe it's important to consider how this happened in order to mitigate any future occurrence. Contributing factors: 1. The gusty crosswind2. My inexperience with Aircraft X3. Excessive speed for the conditionsMitigation Strategies:1. Slow down; get to taxi speed more quickly.2. Understand the only connection to the nose wheel is the tiller and to guard/utilize it appropriately.
Captain reported loss of control while exiting runway at the high speed turnoff.
