Recently bought a 2003 pathfinder se. Dicovered that night the gauge lights were nearly impossible to see in the dark. Blinker/highbeams and other indicator lights all fine but the speedo/tach/fuel/and temp are dark. I bought led bulbs online that should be very bright but they look just as dim as the old bulbs. The dimmer switch seems to function as it gradually gets darker then pitch black at the end of the wheel. When we bought the car there were some blown fuses ive replaced them. One foglight lens is cracked and looks like water has rotten away inside. But otherwise every else electrical seems fine and the battery tested perfectly fine. What can i do?
