I found an old siren in a box of junk I had. It came out of a cheapo Black & Decker burgler alarm kit. I thought about putting it on a bike but it said 12V. I decided to give it a try with a 6V lantern battery and Wow! :shock: It's labeled "120 db/meter" and it is ear splitting loud and does the whoop-whoop-whoop sound. Perfect!
So I opened up the tank to see if the battery would somehow fit inside, along with the horn unit already mounted in there. I did switch the horn unit and put one in that took only one battery to give me extra room.
It fits! Now, how do I mount this fat, heavy battery in there? I really don't want to drill any holes in the tank. I think I would probably drill a hidden hole or two in the frame for a bracket as I'm going to drill at least one hole for a grounding screw anyway. Give me some clever ideas on how to mount this battery. Gary
