Yikes. Thats a bit steep for me being too lazy to flip a switch for my lights. I'll have to checkout Amazon and similar. The problem is everyone just gives part numbers and no details about the parts.
It seems you were (hopefully) right about a connection issue as well, or my alternator gave out. Or driving with the loose connection caused my alternator to go out. Only time will tell. About to go take everything off and reseat and try to track someone down to give her a jump.
My car kept getting down to about 8 V on the way home last night (just barely enough to stay on, in fact, it turns off the radio and other unnecesarry things at that point). I was able to keep it going for a few miles by pulling off to the side of the road and playing with the positive alternator connection on the alternator. Lights would jump right back up, I'd start to drive, right back down. So I gave up and had AAA tow it back here. Something about playing with that positive alternator cable in the rain without gloves which is incredibly close to the block just didn't feel right. So there is a chance I overworked it and it'* dead now. But hey! It'* under warranty, it was worth a shot
