things

i have made a tornado machine/simulator and using led's as the light but after about 20 minutes the led's are quite warm. the thing is though these aren't normal high intensity led's they are actually out of a dead train signal light. there are about 50 on the board (haven't counted them yet)and i think they run off 12 volts under 7 volts they don't light. i was wondering if it is normal for these to get hot or am i over powering them(they still work). i don't think it is shorted because the switchmode power supply hasn't shut itself off. any info would be appreciated.
