Undernead the dash board on the drivers side, us spec.
there is a blue relay this controls the high beams.
on cars with Dayligh running lights, this blue relay is replaced with a bigger looking relay that send 5 volts alternating current to the high beams, so they look dim and act as DRL.
what you seem to be having is a failing DRL relay. they go fro some 80
there's been a post about this issue, just do a search either here, or google.
hopt this helps.
