I have been experiencing severe mobility issues. Several times a month, by the time I get to my apartment door after a package has been delivered, if the driver has not rung the doorbell to alert me they have dropped something off, someone in the building will have come along and helped themselves to the package sitting outside my door. I have made signs of various sizes requesting the drivers please ring the doorbell when delivering, and have made countless phone calls to (yes, even) Amazon, UPS, FedEx, etc. to make sure the directions for the drivers to *please* ring the bell are indeed noted in the driver’s instructions, and that the have a Supervisor request the drivers PLEASE ring the bell, as chances are I am not going to see a notification about the package in time. But the signs and the calls don’t always result in the drivers consistently ringing the doorbell (although Amazon has always been super helpful- their Supervisors have been very thorough in addressing this issue.)Were I not disabled, the doorbell being rung after a delivery would not be as crucial an issue. What else can I do, I thought, to attract attention to the doorbell? I’m working on a larger, more colorful and interesting sign, but I thought- why not add some kind of little flashing light to attract the eye to the doorbell? Delivery drivers are super busy, and they see many doors and doorbells (and, I am sure, signs) every day, so anything I could find to make the doorbell stand out would help.I looked at all sorts of different kinds of small lights before I came across these. I had never seen anything like them before- never knew little lights like this existed. But good old Amazon- trust them to pull yet another rabbit out of their hat. I thought they looked really cool. I was amazed at how tiny they were. The description stated that if you pulled out a tab on one of the spheres to activate the lights, if you replaced the tab, you would “turn off” the flashing light until you wanted it to flash again. That– didn’t seem likely. I’ve purchased many inexpensive novelty items such as this, and was skeptical that something so dinky and inexpensive would come with an “on/off” switch.The little spheres come in a nice box. They are really small- I measured one half inch from bottom to top. I purchased the multicolored ones, which I assumed meant a mix of all the single colors in one box- some that blinked red, some blue, some green, etc. But instead it meant as soon as you pulled the little tab (I managed to lose the first couple of tabs before I learned to be careful to hold on to them) the little globe will blink all colors of the spectrum. The pattern of blinking and color change is really really fast! for a couple of seconds- then slower, like a heartbeat- then slow slow slow… for a few seconds, then back to super fast. They are BRIGHT little guys!After realizing they would be perfect to hang in a small, eye-grabbing cluster from the doorbell, I tied one to the end of a generous length of clear jewelry cord, pulled out the tab, and threw it across the carpet. The cats, who had been watching intently, went nuts! It was like a laser pointer, but without them ever figuring out that the red dot lives in the little box in your hand and wandering off in disgust. They chased it like it was some kind of crazy firefly. New cat toy! I wouldn’t leave one of these on the rug for them to just play with, because it is so small, I’d worry about it being swallowed. But at the end of a cord, sparkling and flicking around, they tired themselves out happily chasing it.I tied a few of these fun little things on a short piece of clear jewelry cord. I am going to tape them to the door jamb near the doorbell tomorrow, after activating them. The doorbell should then (I hope) be impossible to miss. And yes- you *absolutely can* push the tabs back into the little slots, and “turn off” the blinking, then pull the tab out again, and restart the blinking. You can do this repeatedly on the same little ball. I was amazed to see it worked!Back in the 90s, one of my buddies used to go to raves, and she would have absolutely loved these. Necklaces, bracelets- she’s such an artist, she would have probably covered a dress with them. But if you don’t happen to have a rave to go to, if you are going to walk at night with your dog and don’t have special lights, you could use these attached to your sleeves, or hanging from your pockets, or something. And put a some on the dog’s collar.Every one of these I have tried so far has worked. As I have only tested about twenty or so so far, I can’t attest to the viability of the rest of the box. But for the cost of these little things- their performance, and their construction, has really impressed me. Fingers crossed, they will work as a doorbell “lure.”
