Headlights and transmission?

When I get the car to highway speeds and let off the accelerator, I can hear a screaming sound coming from the front driver's side area. If I put in neutral and coast or push on the accelerator the sound goes away. I’ve replaced the driver's side wheel bearing and replaced brake caliper bracket bolts that were missing the washers, so they were rubbing on the rotor. None of that has been any help. I also had the transmission and clutch looked over and they said it looked fine. It also makes a rattling sound in reverse or when it’s cold until it has run a few miles and warmed up.
The other day driving to work one high break went out then a few seconds later the other did. The low beams still worked. Today I switched the fuses and relays from high to low and high still didn’t work, so I put fuses and relays back where they were and now neither low nor high work. Went and got a new fuse and relay to try and get at least low beam back but that didn’t work either so now I have nothing except parking lights.
