Instrument Panel lighting dim


My instrument panel lights are very dim. Even with the light switch turned up all of the way, still all very dim. Any ideas are appreciated.

I remember years ago when I first got my '72 being disappointed in the lights and replacing them with new ones, thinking that will help. Not! LED is the way to fix the situation.


I just made sure I got dimable ones. They don't flow up and down like regular ones but man what a difference.
I couldn't see how fast I was going before changing them.
Depending on what year you have, you may want to change the sockets to a later year, was a bitch getting them back in with the original 74's. Found out afterwards to go with a new year was much more easy installation


The gage lights, rely upon the gauge housing being properly grounded to work, for each bulb. ( first verify ALL your gauges, and center console are properly grounded.)
any resistance equals dim lights,
The gnd from the Gauge housing go to the LT hand door frame,/ birdcage. ( this would be second place to check for good gnd. connections in the cabin).
Then Cabin/birdcage ground to Frame, usually not even connected, located about where your left knee would be under the car.
and finally the frame to battery cable. any one of these corroded connections can have resistance. ....you will have dim gauge lights lights.
if you just stick in Leds, they will be dim too.
