K so long story short, I own a 2001 Nissan Skyline V35 Sedan. As of recently, I just started to get a few electrical problems. 1st one is my Skylines Headlights have been turning on and off by themselves eg I haven't left them on, I havent left the key in the ignition, they just been turning on and off by themselves, they stay on for like 10-15mins and the only way I can turn them off is by disconnecting the battery. I can still manually turn them on and off whenever in need.

2ndly, my dashboard lights just randomly turned off and now won't turn back on, as did my aftermarket stereo that was installed in where the DVD use to be.

Any help would be appreciated
