need help ASAPPPPPP but its not like going to kill if you dont hurry and help haha

Like above^^^
Make sure you have an 1157 in your tailights. On your light switch under the dash, make sure there is a hot wire going to it. As for your horn, what else is hooked into that circuit? It could be just a pinched wire. On the DS, take the kick panel off. Thats where the horn relay is. Identify the color of wire going out thru firewall then make sure its not touching ground somewhere. I think its a green with white stripe wire yours may be different.
