Two of my touch control lamps went bad at the same time. They would work during day time but not from evening to morning. I thought the touch control mechanism went bad. So I replaced them with brand new touch control kits. The result was same – they work in day time but not after evening. I contacted the manufacturer of the touch control kit and asked them what might be causing the problem. They said they have never heard this complain. So I went bought another kit made by Bright Image Corp and the result is same. The lamps work fine during day time but not at night. Can anyone help solve this mystry? Thanks.
