Headlights wont come on??

[Zumo]

Last night I went to turn my lights on and only the parking lights came on. I checked all fuses and connections and figured the only thing it could be is the relay for the head lights. No time to go to the parts store.

So I have to drive home with no head lights(from Ft Worth to Dallas on I-30)behind my uncle so I can see. Then all the sudden about half way there they come on. I was like what gives?! Maybe something had to warm up? I dunno. Anyway I whent out this morning and they wouldn't come on.

Any ideas. I am going to try replacing that relay when I get home today from work.
