All I know of are Cuesta Park in Mountain View - like 9 courts I think. They are free to MV residents but become free to everybody after business hours. Lights turn off at 11PM.
And then there is Wallenburg in San Jose. Lots of courts - like over 9 I think.
The De Anze College courts have lights but apparently they close at 8PM.
The Monte Vista High School courts do NOT have lights.
