Which x-mas bulb is it?


I have a candy cane x-mas yard ornament that's hard to find of this quality plastics and colorfast paint or i would not bother with this question. It's 3 candy canes, 36" tall on 1 electrical run with a male and female plug at either end. The fuses in the plug are good as well as the voltage throughout the run as i tested it with one of those audible handheld voltage testers from plug to plug. There are several dark bulbs throughout and lots of clear ones also.
How do i test these bulbs for working condition.........Tom

I'd bet all the dark ones are blown
I usually use a working set of lights to check others
If you do not replace bulbs as they burn out you end up with a massive burn out as the rest of the bulbs at some point can't handle the load

Ayuh,... Plug a new bulb into the socket,...

The glass part, 'n the little plastic circle nearest the glass, pop out of the sockets...

I s'pose you could meter the bulbs after you pop 'em out of the sockets,..??

That's 57 bulbs to test. I thought there was a quick way to weed out bad bulbs. My bad. So the dark bulbs are prob bad and as more dark bulbs appeared the load increased on the others causing more bulbs to burn out. Right? Do i run a continuity test across the wires of the bulb to check if it is good?

The conunity test will do not any thing good with series bulb due that type of small bulbs they will useally have a shunt in there to bypass the filment when it burn out but once the filment burn out the other remaning lights will get gradually brighter each time a bulb burn out so that why it wise to replace few of them.

to get correct voltage bulb just count how many on that string and dived by 120 volts that will tell you the bulb voltage.

If you still have the label it will tell you what voltage bulb to use.

Merci.
Marc
