Why are my 4 inch sets not spaced 4 inches apart?
Sometimes manufacturers say their sets are 4 inch spaced, but the wires in between bulbs are cut every 4 inches and then the bulb sockets are installed. The wire going into the socket are counted as part of the spacing from the manufacturer, we in turn list them that way on our website. it can be a headache not getting the bulbs exactly spaced how you need, just please take this into consideration when making your purchase.
