Featuring two high-frequency flashing blue LEDs powered by three AA batteries (battery box included), it delivers superior brightness and easy installation with four mounting holes. Designed to mislead potential intruders by simulating an active alarm system, this compact, battery-powered unit is a cost-effective upgrade for enhancing home or office security visibility. ## Description This battery powered Strobe LED can make your dummy siren Bell box alive to mislead potential burglars. This LEDs are flashing in high frequency with very bright lights to produce a warning to the potential burglars. This unit contained TWO Leds therefore is much brighter than those one led unit in the market. The PCB come with 4 screw holes and can be fitted inside of most siren box. The item comes with battery box for three AA size batteries (batteries not included), the battery life depends on the quality of battery, we recommend lithium batteries. The LED work with power from 3.5V to 4.8V DC. Please see below product Youtube video: https://www.youtube.com/watch?v=_MFH2i3MZrM Review: Simple yet effective - Why spend more - Was some what dubious about this item being effective, that being said it does do exactly what it says on the tin, simple electronics and easy to fit in a dummy alarm box, my only criticism would be using 3 AA's makes the power pack quite large compared to others who use smaller more powerful batteries. The LED isn't quite that bright in day light as some other more expensive set ups, this could be fixed if you mounted them directly to the front plastic casing using an LED mount. Mine are simply sat loose in the bottom of the casing so not at the best angle for omitting the full light, However at night they really stand out and cant be missed which is why I got this unit. 9/10 Review: Very simple but efficient. - 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. ## Features - This battery powered Strobe LED can make your dummy siren Bell box alive to mislead potential burglars. - This LEDs are flashing in high frequency with very bright lights to produce a warning to the potential burglars. - This unit contained TWO Leds therefore is much brighter than those one led unit in the market. - The PCB come with 4 screw holes and can be fitted inside of most siren box. - The item comes with battery box for three AA size batteries (batteries not included), the battery life depends on the quality of batteries, we recommend lithium batteries. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QKBZ74R | | Battery Description | Lithium | | Battery description | Lithium | | Best Sellers Rank | 54,721 in DIY & Tools ( See Top 100 in DIY & Tools ) 38 in Sirens | | Brand | QUANAN | | Colour | Blue | | Control Method | Touch | | Control method | Touch | | Country of Origin | China | | Customer Reviews | 4.0 out of 5 stars 182 Reviews | | Manufacturer | QUANAN | | Model Number | NEWFLASHERLED | | Mounting Type | Wall Mount | | Part Number | NEWFLASHERLED | | Power source | Battery Powered | | Sensor Technology | No Sensor | | Unit Count | 1.0 count | | Voltage | 4.8 Volts | ## Product Details - **Colour:** Blue - **Brand:** QUANAN - **Power source:** Battery Powered - **Battery description:** Lithium - **Voltage:** 4.8 Volts ## Images ![Blue Flasher LED PCB with Battery Box for Dummy Alarm Siren Security Bell Flash Box (Blue) - Image 1](https://m.media-amazon.com/images/I/81V3z6dYUjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple yet effective - Why spend more *by M***9 on 3 April 2020* Was some what dubious about this item being effective, that being said it does do exactly what it says on the tin, simple electronics and easy to fit in a dummy alarm box, my only criticism would be using 3 AA's makes the power pack quite large compared to others who use smaller more powerful batteries.
