when we bought the car it was like this. we can't figure out what is wrong please help
 
depending what year it is the bulbs are probably just burned out the filaments gets old and they dim out with time.
 
first off you do need to check the bulbs in it,because both of them can go bad at the same time, secondly if you check them and their good check the dimmer switch it will cause then not to come on bright,that's the most common cause for the bright lights not working,good luck and happy holidays.
 
your low beam bulbs may be burnt out, but usually not both burn out at the same time. You could have a corroded connection at the switch, or even a faulty switch.
 
most likely the low beams are burned out, however check your fuse box / power supply box , some vehicles have fuses for the low beam function, last resort is bad dimmer switch.
