Review on 💡 Incandescent Replacement Christmas Light Bulbs by Kayla Guzman

Know current and voltage for your specific application. You'll need to adjust what's already in use so as not to introduce more lighting issues and burn-in. The label on the filament should give you the information you need to order the correct bulbs. Once they arrive, simply use the same base that the burnt bulb is in and replace it by routing the wires the same way and then bending them to match the bulb base. Replace the large burned out section with the lights off and do not reconnect until you have replaced 90% or more.
