2004 Subaru Forester Dash Lights out. My speedometer and tachometer dash lights are out. Only the fuel/engine temp lights are still working. I need a flashlight to see my speed at night.

It is is intermittent, the reason will be bad connections. First spray that little brightness adjustment wheel with switch cleaner. That is normally the reason. If that doesn't work, check the plugs up behind the dash.

Ignition switch first then look for the ignition relay under the hood.

Dash board ground behind the gauges would be my guess.

if the car stop or battery discharged when the dash light went out then it maybe alternator belt or alternator is the problem

You need a new instrument cluster. Ebay is a good place to get these.

Did you check the fuses?

Check the fuse for the gauges, either around the dash, or under the hood.

Sounds like your clock is dying. This is typically an issue with the clock itself. This is very common with many vehicles, CR-Vs, Pathfinders, 4runners, etc. The good news is that it can be repaired for a reasonable rate, check out www.autoclockrepair.com

On another forum someone said to disconnect the cables from the battery; press on the brakes several times to release any electrical charge still in the system; wait a few minutes and reconnect the battery cables. It worked like a charm--speedometer, tachometer, and display all function now!

just follow the wires that cnnect to the speedometer light and screw to change bulb . thesame as to the tachnometer light there also is awire connected to it .
