Sounds like you will have to replace the sending unit that is in the gas tank with the fuel pump. This is the electrical unit that has the float on it. When you fill your tank the float moves and tells your gauge where the level is at.
You could aways hope that maybe the plug is loose at the tank but unless someone messed with it and broke the plug clips in the past that is unlikely. If you have over 100,000 miles and decide to replace it you should go ahead and replace the fuel pump too while your in there to keep from having to do it down the road later on. Hope this helps.
The floater inside your pump is sticking. You will have to replace your fuel pump in order to fix this problem.
I was told it is your tire sensor. and if it stays on even after you rotate them and fill them up, it could just be broken. I have this problem myself.
The temp sending unit or gauge is bad, probably the sending unit.
A gearbox warning light that stays on even when the fluid light stays on may mean that there is something more serious going on with your car. Your Fiat should be taken to a mechanic to get checked.
take it to a mechanic
It's an output that is set to on by a momentary input. i.e. a pushbutton turns on a light and the light stays on even when the button is not pressed. The output is 'latched'.
Sounds like a faulty headlight on-off switch.
Fuel tank sending unit. Fuse.

Unplug the coolant temp sensor and check what the gauge says...If it falls to cold, then the sensor is at fault. If it stays, then the gauge is either faulty or the contact points on the back of the gauges need to be cleaned...

There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. What is broken light? As far as I am aware, no speed did, or even can, break light.
pull the gauge cluster and check to make sure all the wires are hooked up. if not it will probably be the sending unit or even problems with the fuel pump. pull the gauge cluster and check to make sure all the wires are hooked up. if not it will probably be the sending unit or even problems with the fuel pump.
