IMPORTANT:
A plastic base has been included with these bulbs. This base may not be interchangeable with all manufacturer’s light strings. If you have an issue with these fitting your string, bend down the copper wires on the side of the base and the glass bulb will now be free to slide out. Do the same with your burned out bulbs and you may then swap these new bulbs into your existing bases and bend the copper wires back up to secure them.
