Tail lite has water in it about one fourth full how do I get it out without taking it apart

Get a tiny drill bit - (1/16inch ) . Look over the light assembly and drill into the lowest point, making sure you drill only into the lens and not the housing. **** the bit around a little to remove plastic burrs - this should get the water out. You may want to check with your local wrecking yards for a replacement light assembly as yours has a crack, allowing the water in.The water will cause corrosion in the bulb socket, eventually forcing you to replace several bulbs before you'll have to replace the socket.
