I have some troubles with the radiator light, when I start the car it keeps on until 5 miles or so, after that the light tunrs off, once i refiiled the coolant liquid until more than max and the radiator light is fine now, but after driving one week, (200 miles aprox.) when driving some liquid leaked while driving ( 1/4 GAL approx.) and the radiator light is again on, what oculd it be?? 
, the temperature looks fine,
RMRWelcome to the CEG!
Your light will stay on until the coolant gets hot and expands in the overflow container and becomes high enough for the coolant to cover the sensor that is causing your warning light to come on!
As you said yourself, you have a coolant leak and until you get that fixed, your warning light will keep coming on when your coolant drops below the sensor in the overflow container!
Fix the leak and maintain the coolant level just above the MAX of the overflow container.
