'93 240SX Headlight fuse blowing

[S14Dorikin]

Ok, The other day I left work and turned on my lights and noticed the right side light was out. So, today I went and bought a new lamp thinking the bulb went out. I replaced it tonight and the light didn't work. This is where I say "F**K! Not an electrical problem!!" So I checked the RH side light fuse in the engine bay, sure enough the 15amp was blown, I replaced it with a 15, turned on the lights, instantly blew before the light could come on. So I tried a 30amp just to see what would happen. It went on, so I went to leave work and poof it blows 10 in less than 10 seconds. Anyone have this problem before? I'm guessing the plug is either corroded or the ever so scary short SOMEWHERE in the wiring. I'm gonna check it out in the morning, its too dark now. Thanks.
