Do you have a festoon light set but don't want to place a bulb in every bulb socket? Then this black blanking cap is the solution. You simply screw the stopper into the bulb socket, just like a bulb. This protects and seals the bulb socket from moisture so you can choose where you place your bulbs along the cable.
An easy way to set up your festoon cable's light effect exactly as you want it.
