Light bulbs are located on fixtures — each holds 3-5 bulbs and can block a part of the field or just rest in a corner. To remove the light bulb from the socket, match pieces of the same color next to it. The rest of the bulbs may change their color as you progress. Once all the light bulbs are removed from their sockets, the fixture will disappear from the field.

NOTE:
Multiple explosions will not affect more than one bulb.
