Package includes: enough mini Christmas light replacement bulbs, enough to replace broken bulbs on your Christmas tree lights and to save for a rainy day.

Size details: the base is 1.09 cm long, 0.76 cm wide on the inserted part of the base, and the bulb is 3.2 cm long, 0.5 cm in diameter. Please check the specifications of your own bulbs carefully before purchasing.

Specifications: 2.5 volts, 0.425 watts, 0.17 amps. Mini incandescent bulbs for Christmas lights are made of good quality material and are well inspected and tested by the manufacturer, designed for 50, 100 or 150-light strings.

How to replace: first, make sure your light string is unplugged and remove the broken bulb with its base and discard it. Then, check that the two wires on the new bulb are correctly positioned on either side of the base (do not let them cross or touch each other). Then insert the new bulb at the correct angle and make sure it is fully inserted. Finally, plug the string back in to see if you have succeeded.

Applicable occasions: our mini Christmas light replacement bulbs are suitable for artificial Christmas trees, wreaths and garlands. Perfect for replacing existing bulbs that have broken or become old. Warm tips: if the plastic-coated housing does not fit your bulb, use our glass or our wire in your original plastic-coated housing.
