Hope someone can help me. I'm making a fire truck cake for my grandson. How do I put flashing lights and a siren on it? What kinds of lights would I buy to do this? I have looked all over for something that I could use for this purpose. I don't reallty want to use lights with a wire how would I cover the wire. If anyone has done this on a cake please let me know the secret.

I don't know how you could do that....but I have a suggestion. Why don't you melt some hard candies in the colors that you would need for the lights that way when light shines through it looks brighter, like the lights are lit up
