headlight problem
 

hi,

theres something wrong with my mom's 01 montero xls' headlights. first the passenger side headlight was going bad, we thought we just had to change it, but when we did, it was very dim even though it was a new bulb. then a few weeks later, the driver's side headlight went low too, and we thought the same, maybe it needs a new bulb, so we change it, and its also low even with a new bulb. please help.
