We purchased your Hampton Bay Alexandria motion sensor porch light in white years ago. We assumed it would last for a very, very long time as it appears to be well made. Sadly, the plastic piece that covers the sensor cracked and we had to remove it because it looked unsightly. Now, with the plastic removed, the sensor is exposed and that certainly doesn’t look good either. *We simply cannot understand why this would happen, as the light is mounted under a covered porch overhang, and is only briefly exposed to early morning sun. *Is there a warranty that covers this kind of problem*defect? Is there a replacement plastic covermpiece that we could get to replace the one that cracked? *It would a blessing for us to not have to buy another light. I’ve already looked for the same exact model, as it complements our home’s design and they run almost $**. I hope and pray that you can help me find a solution. *Thank you so much!
