Shop for Mini Lights
Heavy duty light strings. Plug 6 sets end to end.
Most strings come in 2.5, 3, 4, 6 inch spacings. Bulb spacings can vary depending on the style of manufacturer so all measurements are approximate.
Mini light sets with end to end plug allow to you plug 3 to 5 sets together. No end connector sets are called craft light sets and feature only a single male plug.
99% Of all current mini light bulbs are shunted, so if a bulb burns out the rest of the string stays lit!
If a set goes out and there are no burnt out bulbs, most of the time it's a loose or twisted bulb. Gently tap and or twist each bulb in the unlit section to find the culprit.
