Outdoor Dusk to Dawn solar light ?

Question:Hi, I am going on the second solar light by the back door entry since the first one did not last long. I replaced one and have it installed by a professional this time. It is dusk to Dawn system. I was working well for a while, now the light bulb went out. I replaced it, the light is ON constantly even during bright day light. What is going ON? I am tired of having have to replace the fixture over and over and over....what is the problem ?

Answers:
Just install a reg. motion sensor light, and point the lights, and the sensor as close to covering the back door as possible (make a tight "Trap Zone" by the door), this minumizes falsely triggered "Lights 0N", by blowing wind and branches, set the lights for 1 min, if anyone hangs out for any longer, they will remain on at night. "Solar powered lights have an "L.E.D" bulb that should last forever.
