It may seem like a good idea cost effective and simple.
Can you replace incandescent christmas lights with led.
However the wiring for your classic lights is different and unsuitable to handle leds.
Incandescent bulbs have little wires popping out of the sides of the base of the bulbs.
So in this instance the answer is yes you can mix the bulb styles.
We have all heard that led s light emitting diodes will soon replace traditional incandescent light bulbs and the more recent cfls compact fluorescent lamps.
Led lights if they are replaceable don t generally have the same style base but will be bigger and not have those little wires.
In parallel wired c7 and c9 stringers you can mix incandescent and led bulbs to your heart s content beyond the electrical specifications taste and christmas light decorum are your biggest considerations when mixing bulb colors and styles.
The short answer is no.
You can t use led replacement bulbs if you can find them to replace traditional mini lights on a traditional light string.
You could alternate painted blue or opaque bulbs with led bulbs for different textures in your lighting.
Incandescent light bulbs are generally made of glass instead of plastic polycarbonate.
