I own a set 100 and now this set of 200 lights. The set of 100 for a year now. I decorate the outside of my home with these lights for Christmas since I live in a sunny state. I'm amazed to see these lights still blinking more than 8 hours after they come on. I've owned other lights that are only on for just a few hours only. I LOVE these lights.

For some reason they flicker like a strobe light at certain times.

The lights worked for one day. When I push the button, it just blinks. I would like to contact the manufacturer but can not find their information.

They have 3 LED's not 6 and either flash or off. Granted a cheap novelty item but it would be nice to get what is described, try keeping them on with constant flashing.

I didn't know that my brake lights were on the blink (pun intended) until my cruise control started freaking out.  I replaced the switch in less than 5 minutes and now everything is bright and steady.

They only blink like crazy! It is ridiculous that there isn't a setting to just have a constant on mode.

I had brought 12 of them to swap out in interior lights in my car. Out of all of them, three functioned normally. The rest of them were either dead on arrival or flickered like crazy once they are on for about a minute or two.

Update: June 2017
The lights were actually ok. It was a bad batch of 12 volt, 6 amp power supplies that turned out to be the problem!

Original review:  The 12 IR illuminators (but not the 24} appear to have some sort of defect. One of the 2 I bought worked fine for several weeks, then blinked on and off instead of staying illuminated. It didn't matter if the "always on" button was pressed or not. The other one did the same right out of the box. I use the 24 bulb version with the same type of 6 amp power supply, and it worked great since day one, even though it draws twice as much current

I too think the flashing red light is a bit much. I wish it was a smaller, more non descript light. I don't necessarily want to draw attention to these, which I'm sure is the point for some folks. I contemplated whether to install the batteries or not for a few days and finally decided not to. I have these mounted so that they could be seen during the day (without the flashing red light) and at night I have them by a motion detected light which should provide enough light so someone would see the cameras are there. These are just an addition to my existing (legit) Arlo cameras for an added layer of deterrant.

I can't believe how well these light up with the solar panels.  Even at 4:00am they are still changing colors!

Editing original review
After about a year one of the 3 lights has gone nuts and blinks off and on all the time.
All are mounted under our front porch ceiling and protected from the weather.
It stays on in day light or dark and constantly blinks on and off.
The other two appear to still be working fine.

Could this be a low battery issue ???

Pretty nice lights.
Like the idea of the D Cell batteries which it takes 4
Throws a pretty bright "circular" light but does not throw very far which is typical of current LED units.
Have one in a utility shed that does not have electricity so it snaps on when I enter in the dark and lights the entire area (12' x 15') enough to see.
Have one mounted over the front door off to the side so when someone walks onto the front porch it snaps on to light the way.
One mounted in the attic to light the stairway ladder until you get up high enough to turn on the attic light.
Will be purchasing more as needed.
Nice lighting source.

I just received these in the mail. As of right now they are just ok. I noticed my old lights run at 7w. These new ones run at less than half that. Since they use less wattage, they blink faster. Same thing as when you have a light go out. Less lights = less wattage = faster blinking. I might be able to live with this. So next I will see how bright the brake and reverse lights are. Then I will update this.

I bought a 2 pack of these hoping to use them for extra brake lights on out motorcycles, and one of them already has about a third of the leds not working. I thought maybe it was too high voltage, but the most I have seen is 13.8V. Now I don't know if I can trust the one that works to last. I have bought a couple of the white cob lights from a different seller and love those, but not these.

I didn't have problems with the lights going out. Yet. It's been a year though. It made a nice addition to my sons big boy room. I do have a problem with the erratic blinking. It drives me crazy and I could only imagine how it stimulates my son. It's on with another light on in the room to reduce the strobe like feel. I wish there was a setting allowing it to be on low, high and blinking. Also, the blinking is out of pattern. I tried to use it as a color/pattern teaching tool.

They look pretty convincing. The RED blinking LED looks... suspiciously fake. Ironically without the LED blink feature i think they are a better deterrent.

I got about 2 months LED blinking on 2xAA alkaline batteries. Very easy to replace (assuming you have a ladder to access the top of the 'camera').

The lights start flickering almost immediately.

I have ordered a total of seven 8W bulbs and so far two have failed.  I haven't got six months out of these bulbs yet.

Update 05/30/16:  Noticed today one of the bulbs started blinking and flickering on it's own.  Now to check out the warranty process which will probably require shipping it back which will cost more then the original purchase price of the bulb.

Original Review: They are an ok LED light bulb.  I have been getting a slight flicker with these bulbs where I wasn't with a other dimmable LED bulbs.  I have since moved these bulbs to my outdoor light fixtures where the flicker won't be a big deal.
