Its not the led's problem, you simple wired it wrong. You wired it so that the led is "hot" all the time. You need to run a hot to your switch, then the hot running from the switch will connect sirens lights and the led all together. That way when you turn it on those all come on, and when you turn it off then the led will go off. Its a simple procedure, but if your not experienced then its easy to mess up to.

Almost great.....cannot be seen in direct sunlight! Radio Shack needs to enhance the tech specs on there products..!!

I am writing in responce to the last revier and would like to say that that is impossible. You may have a NO/NC Switch in which there are two on positions. This is a wonderful product and has no flaws.

Im not real happy with this product, I tried to hook up a siren and lights to a toggle switch and the led's so whenits on the led is on, the only problem is that when you hook it up the led is on when the switch is off
