On approach to Runway 30L; we noted at about 25 NM from runway that we had the VASI in sight.  Unfortunately; as we continued the approach; we realized the lights we saw were the scoreboard for Levi's Stadium which lines up with Runway 30.Notify aircrew of possible confusion with football stadium lights.
B737 Captain reported he confused Levi's Stadium lights for SJC Runway 30L VASI lights.
