Sold in each. Easy to use. Manufactured by Everready First Aid. Made in United States. Review: It works - Our Otoscope stopped working after a fall and replacing it was just not in the budget. I did some searching online and found that sometimes the bulb just goes out. For 14 bucks, it wasn't going to hurt to try. It came in very quickly and after we swapped out the bulb, it worked like a charm! I'm glad this part was so easy to track down and the install was a wiz. Now we are up and running in almost no time at all.

Some are threaded some are not. I would recommend a lower cost generic blub to match the bulb number, and then consider the more expensive and longer lasting blub ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works *by J***B on December 12, 2023* Our Otoscope stopped working after a fall and replacing it was just not in the budget.
