usa car, ? lighting varies by country.
DRL, does car have DRL , Daylight running light open, or as seen in Canada by law mandatory?
the tail lights have there own ground, so would not be loss of ground ,front of car and rear at same time. hard to believe possible same time.
note that low beams, are tail lamps too. same circuit, so when lows fail, front, tails go with it.
in my web site, search box, type DRL , see first photo schematic, 1995
page is how to defeat it but makes fixing easy to. testing.

DRL , top fail item on this car, (it self bypasses if hand brake set or Alternator fails and GEN lamp glows in dash.)
ONE More test you failed to do. is.
Head lamp passing mode, pull the HD lever back and it bypasses DRL. This causes blue head light high beam blue indicator to glow and both head lamps to glow high beams, if yes, then HD have power and the ground is good.
good luck you finding the cause, but first tell if DRL is there. (you'd know this if car was driven many times, if DRL is present for years)
