__NOWYSIWYG__ The Christmas Horn is a horn that is first received from Santa Claus of White Mountain. Once you have received it from Santa Claus, you can buy it from a Parts Shop although there is no need to do unless you sold your Christmas Horn at the Recycle Shop because your teammates cannot have horns equipped and you cannot have more than one horn equipped at one time. It sounds like bells being shaken. Like all horns, it has no effect while driving.
