my stop light is on solid all my lights are working what would make it stay on... brake fluid is topped off as well.... 1985 gl-10 wagon (now running great thanks turbone for the injectors)

My Touring wagon does that from time to time, and All I do is pull the brake pedal up with my foot and it starts working fine. It's a cheap thing to try if anything.

i mean the dummy light on the dash that tells u when a light goes out i think...

Ya that's what mine does, the light by the windsheild wiper leaver but on the dash, the big red light that says "Stop light" or "Stop lamp"

The brake fluid reservoir on the master cylinder has a float in it that tells if fluid level is too low. This float tends to stick in a "down" position. Quick fix (assuming level is OK) is to poke at the float with your finger/suitable object to get it unstuck.

i poked the float and it still is lit up.... and i tried pulling the pedal... all my brake lights work so im just a little confused unless it knows something i dont... im gonna set the car on fire soon:Flame:

Mine is on at least 50% of the time. I have a 1986 GL wagon, 4WD 5-speed, carbureted, non-feedback, non-FI.

 

All my lights are in top condition, recently tested & inspected. Stop light still comes on, stays on.

 

It's been coming on for years & years and seems to indicate nothing, other than some funky electrical thing somewhere that is no big deal (other than it's a mystery).

 

If your lights are in perfect working order I'd just ignore it.

My stop warning lamp was on, it turned out to be the coil bulb sensor thing at the rear. It only came on when I pressed the pedal so I think your problem is different.

One of the bulb sockets has corrosion on the ground side. Not enough to make the lamp not work, but any imbalance will cause it too light.

 

The other possibility is that someone wired in a trailer wiring adapter that combines brake and turn lamps, and the box is not functioning properly anymore.

you know there is a trailer light harness in the back trunk area... but it doesnt look to be completely wired ....

If one of the turn signal wires is hooked up to it and the other is not, that will make *stop* lamp light for sure.

A bulb issue should only cause the STOP light to light when you step on the brake (i.e. try to use the bulbs), at which time the imbalance will be sensed. On continuously would indicate the reservoir float circuit, or (not sure if Subarus have them; Datsuns do) the pressure switch on your diagonal braking block shows a problem.
