Notification setLights() Default Value?

I want to create a custom notification. So i want to change the lights and the tone. I use the NotificationCompat.Builder for that.

Now i want to change the Lights via setLights(); Works fine. But i want set the default value of the onMS and offMS. I haven't find something about that.

Can anybody help me to find the default values? Here is the documentation for that: http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#setLights(int, int, int)
