Light Up Puzzle

Puzzle "light a light" (also known as "Light Up", "LightUP" and "lanterns") is a rectangular box in which some cells are white, some black. In the black cells can be numbers from 0 to 4. The goal of the puzzle is to place light bulbs in empty cells so that all white cells were illuminated.

the Light from the bulb is distributed in a straight line horizontally and vertically until you hit a black cell or the border of the field. Bulbs should not illuminate each other. If a black cell is a number, then it must be adjacent (left, top, right or bottom) a specified number of bulbs, no more and no less.
