Blue Flasher LED PCB with Battery Box for Dummy Alarm Siren Security Bell Flash Box (Blue)

I have bought 4 of these and very happy with the performance. I use Lithium batteries as they last longer and the LED'S are nice and bright. Easy to install. I use double sided tape to attach the units in the dummy box or you could hot glue them.Only downside the intermittent flash is a bit slow but other than that I am very happy and looks realistic at day and night.

We didn't get this to use as a siren light since most burglars know that sirens and security cameras rarely have flashing lights and are just fake. We simply leave it close to a window when we're away. It gives the impression that there is another and different security system inside as well as outside. So far it's very impressive and the light powerful enough to be seen through curtains.

Paid extra for next day delivery. Arrived Faulty. Sent back the next day. Save your money.

Bright lights, someone would walk passed rather than take a chance

Bought as replacement part for dummy alarm box. Very good value, as described

Cannot see the light in the day time. Works at night only but not far away, my alarm box glass may be to thick.

Easy use. Battery life is good, if you use decent batteries. Very bright in the dark. I used this as part of an alarm system. The lights light alternately. I was that impressed and I purchased another one. Having used this for some months now. I have encountered one issue. The black and red wires break at the solder joint on the board quite easily. This is poor quality soldering. It’s then just a case of re - soldering yourself making it a much stronger joint.

Works we'll inside a dummy alarm box on the front of the house. Put two lithium AA battery in, so should last a year.
