Condensation on face of tach

[Mwood1129]

Is it normal for the tach to condensate only when the lights are on ? I do live in the southeast and the humidity is very high . It’s the only gauge that does it .

First of all, is your Jeep in a garage ? Cool dry place. Mine is and it happens all the time, especially down here after rain storms, hot and humid like a Beach here, just no sand. I just turn my defroster on and fan high and usually gone in 10-20 minutes. My tach is aftermarket and is usually not a problem, usually all the factory ones are my problem. For me the defroster is the cure

Yes garage kept. And a factory tach. I just know the factory tachs are getting harder to find. I may try a L.E.D bulb and see what that does .
thanks for the information
