Answer
Immediately after the switch closes, the light glows intensely bright,
and then, with time, the intensity of the light diminishes, until eventually it stops glowing altogether.
Work Step by Step
After the switch is closed, the current will flow through the branch with the light, until the capacitor plate accumulates enough charge on its plate (until the capacity is reached).
From that moment on, the capacitor serves as a block for the (DC) current.
So, immediately after the switch closes, the light glows intensely bright, and then, with time, the intensity of the light diminishes, until eventually it stops glowing altogether.
