Mig750

Couple of months ago my regular lights stopped working. Inside would indicate the lights were on but nothing. High beams went too but when i put it on high beam the regular lights come on. So I have been driving around with reg. lights highbeams switch turned on. Any thoughts. Also my factory alarm siren stopped working. No sound but lights still work. Where is the siren for a stock alarm? I want to check the connecting wires.
