Gauge light question
 

Greetings,
1972 Blazer with Tach dash.
Does the oil pressure gauge have significantly less backlight that the other gauges?
Speedo, Tach and Fuel gauge are properly backlit.
Left side gauges, battery and Temp are a little less than the speedo/tach/fuel gauges but are decently lit up.

Right side gauge Blank and oil pressure is barely lit up.
Doesn't appear as though any bulbs are burned out.
Any tricks to getting more light out of the left side gauges?
Thanks
Tbruz

On mine when this happens it always seems to be a bad bulb, as they dont have individual bulbs per gauge, I guess in a way it's nice to not lose illumination completely when a bulb goes out, they seem to still get a little light from the other cluster lights, had to get to one yesterday, not fun
