I contacted Westek but never got a response. I followed the instructions on how to assemble it and had to make numerous modifications to make it work. With the 3 "D" size batteries in the head it makes it very heavy and prone to damage from strong winds. I had to cut pieces of thin pieces of plastic to add to the back cover so that the ribs would make contact. All in all I had to spend over two hours to make modifications so the light would operate. DO NOT EVER BUY A WESTEC PRODUCT.
