Replaced rightside lowbeam....later that night notice hibeam went out. Replaced and checked fuses in engine compartment.

1 night later driverside lowbeam has blown....son has car so couldn't look at tonight but he thinks parking lights went out also. DRLs seemed fine.

Any suggestions or thoughts as to what I should begin looking for to diagnose why all of a sudden bulbs are blowing out? Thanks....
