Silly question, I know.

I have a previously owned '94 ram 1500. In the dash above and to the left are two buttons on is labeled fog lamps, the other ( I've discovered is the overdrive on/off button). My question is when the button is lit, is the overdrive off or on?

When the light is on, OD is off. Turn it off when you are towing or hauling heavy loads.

Thank you.For me that is confusing, light on means off/ light off means on.

All you have to do is watch your RPM at 65 mph when you push it on and off, RPM go up when it is off. My 96 V10 works the same way. The reason the light is on is a visual warning that you have OD set to off as you will get worse gas mileage running the higher Revs.

Also, why have the light lit full time when it is in its normal operating status of on. This applies to many vehicle functions. Normal fog light position is off, lights up when on. You will find many things on vehicles where the light is on for the NOT normal condition. So for instance, my wife's Jeep has lane control. I never use it, light is lit when off. Same applies to Sport mode, normal is not sport mode, light is on when in sport mode.
