Step 10: Glue it together
Now put some glue around the edge of the base of the horn. Put it on the botom of the altoids tin so that when it is mounted, the LEDs face forward. If you are using glue that takes a while to set (like my E-6000), you will need to tape the mount onto the tin to prevent it from moving around while it dries. My glue set a decent amount after a few hours, so I removed the tape for the rest of the time.
