Why are my car headlights so dim even after replacing bulbs?
Even with new bulbs and restored lenses, low beams can remain so weak that drivers can barely see a few feet ahead or notice any beam reflected on the pavement. This poor night visibility forces drivers to rely on a low-beam and fog-light combination just to make out the road ahead.
