first post here guys, first Mustang as well, very helpful site. hoping someone can help with a headlight issue. just bought my 18 year old his first Mustang. 2003 Gt, True Blue in color, beautiful! We saw battery terminals with some corrosion, so was going to clean but decided might as well replace with new. He's driving down highway tonight and his headlights as well as dash lights started flickering simutaniously, but not all the time. I may want to add we have no hi beams at all which I feel is probably fuse or relay but probably not related? Terminals are as tight as a frogs ass...so... maybe first sign of alternator going bad? seller had aftermarket stereo put in and took antennae off for looks, so my second thought was faulty wiring or ground? Please help.

My vote is the light switch. At least start there as it is common to both.
