drivers side low beam is dimmer than passengers side. replaced bulb but same problem exists

My car has 210000 miles.
My car has an automatic transmission.

Did you see any corrosion or a broken connector on the dimmer side? Corrosion can build up in the circuit and rod the bulb of voltage causing a dim light. A technician with access to a wiring diagram can trace the power feed along the circuit to track down where the voltage loss is coming from.

Also, you must replace bulbs in pairs as a set of bulbs (high beams or low beams) can generally be found along the same circuit, so when one side is affected, the other side may not be far behind.

If you’re unable to pinpoint the issue yourself, consider hiring an experienced technician like one from YourMechanic who can come to your home or office to diagnose the issue with your low beam lights and help you fix them as necessary.
