Headlight / Horn Advise
 

Guys, Could use your thoughts on this.

Went for inspection today and they said horn and right high beam doesnt work. Went to check fuse and both are burnt out. My wiring insulation on the right headlight are all frayed and I saw one of the wiring to the headlight half torn so I tried to splice it. Didnt fix problem. Should I just replace both headlights?

Would it be easier to just replace the lighting harness? Do you think the horn and the high beam are connected?
