Looks like it. We get a back view of the actress, but she is wearing a white and black costume that resembles what a Doctor Light's would look like in the DC small-screen universe. We know Doctor Light, ex-S.T.A.R. Labs employee Dr. Kimiyo Hoshi-Light, will be making her debut on The Flash this season.
The "classic" Doctor Light is a villain named Arthur Light who troubled The Flash, the Teen Titans and other DC heroes. Eventually a female version was introduced named Kimiyo Hoshi, who was a hero and served on the Justice League International. In the New 52, the pair were revealed to be married -- although Kimiyo hasn't yet appeared as Dr. Light in the new continuity. Prior to the relaunch, Arthur Light had become one of DC's most controversial characters, loathed by fans for his role as a rapist in the best-selling miniseries Identity Crisis.

Barry partners with S.T.A.R. Labs and dedicates his life to protect the innocent. For now, only a few close friends and associates know that Barry is literally the fastest man alive, but it won't be long before the world learns what Barry Allen has become...The Flash.
