of the conductor is above the blade and the portion of the conductor that intersects the light bulb is below the blade the portion of the conductor that is on the opposite side of the bulb extends through the second slot and is above the blade as shown in fig1 it is not necessary for every bulb to be placed within a hanger it is only necessary to place sufficient bulbs through the hangers to hold light string in place as desired which usually means that sufficient hangers are used so that the light string will not materially sag the light bulb may be any light emitting device such as an incandescent bulb or light emitting diode most commonly the light bulb will be a small incandescent bulb as used in common light strings it is not always necessary to insert a bulb through the annular void as shown in fig1 the hanger may be used to hold sections of the conductor without a bulb by routing a portion of the conductor over the blade and an adjoining portion under the blade and through the second slot and then over the blade the length of the slots as shown adequately hold the conductor as shown in fig2 a series of hangers may be used to hold the light string 22 in a gutter 24 or similar structure on a house the light string is.
