What they *don't* show in the picture is how the plug sits at the back of this light (and has the electrodes that control the signals to the lights). If this one is designed like the Cl*pBr*te, the weight of the light causes the light to bounce out of it's bracket. You can use a rubberband to hold the light against it's own bracket, but as the band stretches out, the lights tend to "turn on" or give incorrect signals at the wrong times (like when you go over a bump).

If you're runs better than mine, will you post the company who made it?
