ABSTRACT:
A lamp assembly for Christmas tree light sets, including a lamp socket having a positive metal contact plate with raised portions and a negative metal contact plate on the inside, and a lamp bulb threaded into the lamp socket to force its ring contact and tip contact into contact with the negative metal contact plate and the positive metal contact plate, wherein the lamp bulb has a plurality of grooves spaced around the topmost edge of the ring contact, the grooves causing the negative metal contact plate to make sound when they are moved over the raised portions of the negative metal contact plate during the installation of the lamp bulb in the lamp socket, so that the operator can sense that the lamp bulb is threaded into position when no sound is produced. The lamp bulb has a patterned outside wall formed by: adhering patterned strips to the outside wall of the lamp bulb, then coating a color paint or the outside wall of the lamp bulb and the patterned strips, and then removing the patterned strips from the outside wall of the lamp bulb after the coating of the color paint is dried.
