general problems of the 2002 Acura TL

My Acura Tl's lights work and then don't work all of a sudden. The right head light will go out, and then when I try to turn off the lights and turn them back on the left light will go out and the right will come back on, and back and forth until they both go out and won't come back on until I leave the lights off for about 15 to 20 minutes. Another thing I'm concerned about is my horn, it works at certain angles but doesn't work most of the time and when it is aligned straight. I was on ih-35 and an 18 wheeler was changing into my lane and when I tried to honk my horn to let him know I was right next to him it wouldn't work. If it wasn't for no cars being next to me I would have crashed to the cars next to me or the 18 wheeler would have crushed my car with my self and my kids in it. Another thing is that the horn is also a problem to a 2001 Acura Tl my friend had and I have asked other people that I have seen that have the same generation as my Acura Tl that if there horn works and they have had the same problem. I really think that it is a safety concern simply because if someone would be in the same situation as I was it could easily be an accident. If it isn't a safety concern then what would be the reason for the inspection not to pass if they don't work. . .
