I bought two of these light bars as an additional boot light. The motion is very smooth and the lighting bounces when you open the trunk usually directly, but no later than when you put your arm stretched out. With two light strips of the trunk is well lit - if you like it bright, but will probably have to buy four pieces because the bar is not particularly long. The three legally quite small adhesive strips which are each "pre-installed" for attachment, I have replaced by a continuous strip of carpet tape and since then hold the bars even when poachers ride bombproof. Alternatively, small little screw are attached for a permanent installation. Unfortunately, the bar does not have an additional switch. In the picture it looks also as if it were a more noble materials, such as aluminum, -. The bar is only plastic. For the purchase price but totally ok! :-)
