I bought two and had a previous DC power supply from a previous light bar that no longer worked. I tried plugging in one of these new strips and it didn't work so I tried a different one and it didn't work either. So I bought two new DC power supplies (PLUSPOE 12V1A AC DC Switching Power Supply Adapter 12W) which are listed as one of the power supplies that can be bought with these lightstrips and these strips still don't work. I see no point in contacting the seller or the company as these are very cheap bulbs to go through all the hassle to even fix this issue. but i thought i would share my experience for those who are thinking about buying these lightstrips. I would not recommend it.
