instrument cluster lighting?
there was 0 lighting on tha instruments when i bought this car so replacing all with 194 leds.. discovered tha lamps in it were all good and lighting up when called for.. still no lighting showing up on gauges???. so cleaned tha whole package up and install all red leds.. they all come on ok but still no lighting on gauges??? have checked everything with how its assembled and can find nothing wrong?.. it can only go together one way that i can see because of tha clock stem.. what tha hell am i doin' wrong.. gettin' kinda frustrated...............
after some experimentation making tha room completely dark there is justa tiny bit of red light showing on tha gauges.. white is a complete no show... this is with 12v direct to tha circuit?

Hopefully the new circuit board solved your issue.
If your lights are still dim I would suggest reading the voltage at each light With the dimmer at full brightness you should be getting 12 volts.
Let us know how this is coming along.
