Shudyear Car Solar Power Simulated Dummy Alarm，Anti-Theft LED Flashing Security Light Fake lamp with USB Charger Port，Car Accessories for Most Cars,2PCS (red)

Five star review. Have had these for over a year and a half and have only charged the battery once to do a test run. Confirmed to work so long as the mini solar panel recieves sunlight. These dummy alarms are simple yet more vehicle owners should use them. Very cheap and inexpensive but design wise is very smart. These are mini and compact and placed strategically in the vehicle it can look like stock or even if your good, totally hidden until nightfall and the light starts flashing. Has a simple on off switch and a type C port for charging as a backup. Has a removable adhesive tape on the buttom and can be mounted that way but make sure it's getting sunlight, best placed flat. The light blips and timing look and act like a real armed alarm system. Brightness is viewable if your standing outside the vehicle and good for at least 10 ft away. Not too bright or too dim, blips for less than a second. Stops for about three seconds. If your vehicle doesn't have a visual little dash light visible from outside then these are highly recommended. Even if it's a bluff it still works. Probably for interior use only because of the charge port and outside rain etc. Best used on dashes or rear decks for sedans.

Works great. It is very bright and visible from a far distance. Blinks approximately every 4 seconds. Mounted it on the back of rear view mirror.

Nice design. It's a shame it doesn't blink in daylight. This is assuming that nobody breaks into your car except at night ... which is a foolish idea. I have used black electrical tape to cover the solar cell/daylight sensor. I charge it with USB and it lasts a long time and ... yes, the blue light can flash all day and night on a full charge. INTERESTING: The blue light is many times brighter than the red one.

No issues so far after five months. Solar charging works great. I charged via usb when they first arrived. Haven’t had to mess with them since.

I purchased these for my Kia because juveniles in my neighborhood have been testing my car doors. These lights are very helpful! The blue blinking light is definitely bright at night. I placed one on the back of the rearview mirror and another on top of the driver’s side dashboard—it’s very convincing. About a week after buying these, I went ahead and bit the bullet and got a real car alarm installed, which set me back almost $550, but it was absolutely worth it. Now I have three lights blinking rapidly..two solar lights and the real alarm indicator and I still keep my wheel lock on at all times.

Works just fine. Charged up quickly out the box, too. But the adhesive used for these are a strange foam that you can't really use multiple times. So once you stick it somewhere, it'll grip really well, but don't expect to be able to use it again if you want to peel it off and put somewhere else. Don't be like me who put it on their dash for a few days but wanted it somewhere else, peel it off after a little strength, only to find the foam adhesive completely torn up and unusable. Didn't leave any residue luckily, but now I need to buy some double sided tape...

I was a little apprehensive to buy these due to some of the reviews, here is my experience- THESE ARE WONDERFUL! I mounted mine on my rear view mirror and dash above the stereo. They are super bright, charge during the day or you can use the usb- I haven’t need to do so yet, I’ve seen complaints of them not working after a few days but I think that’s due to not being turned off when not in use. I’ve had my car messed with several times at while parked at my complex but not with these bad boys! I also bought a dash cam but haven’t even installed it yet because these seem to do the trick. Definitely worth the few dollars spent!

It’s not a good product. Battery life is short. Too small to be noticed.
