How do you tell which light bulb is burned out and keeping lighted Christmas decorations from burning.?

Question

I have a teriffic train that is not fulled lighted and a snowman with the top half off.

What am I looking for to replace these bulbs?
How can you tell if its a fuse?

Answer 1

If its a clear bulb, if you look at each bulb you can usually see if the film wire which is what lights up, is broken, or missing. Compare it to other bulbs if in doubt but its very similar then when your household incandescent light bulb burns out. Light sets usually come with 1 or 2 replacement too so keep those handy. My mom usually just restocks the burned ones at the sacrifice of one strip of lights.

Answer 2

The best way is taking some other lamp with the same bulbs and test every one of them. You also could use a voltmeter and find the break of the electrical stream.
