This is the second purchase of a Custom Dynamics Knight Riderz Light Bar... It has worked so well on my first bike, when I bought a larger bike, I had to add one to it as well!  The sequential light is VERY noticeable even in daylight, but really pops at night! Same thing for the strobe effect when you apply the brakes... ATTENTION GRABBING! Very pleased with these light bars!The unit is the perfect size for most bikes, and can be adapted to work just about anywhere you have a flat surface - 4.75" wide and only 0.75" tall, but mounting must be flush against the something (3M tape is on the back of the unit, not top or bottom).My Honda Sabre's stock brake-light is not very bright (even with an LED lamp installed), so adding this light kit really supplements my running and brake-light needs.  I did not have a good surface choice for mounting this light, and I didn't want it on the sissy bar because my tail-bag would cover it when traveling.  I purchased a chrome license plate cover which was wider on one side, which provided the perfect mounting point for this light!  Find the center on the frame, drill a 1/4" hole, thread the wires through the hole, and press the light bar onto the smooth chrome... Yes, it is that simple to add!  I use Automotive RTV sealant to fill the hole and keep the wiring from moving around at the frame hole, and it also improves water resistance where the wires enter the light-bar from the back.  Wiring the light is easy if you have a little, basic knowledge of 12V-DC electrical systems... Black to ground, Red to Brake-light wire, Blue to Running-light wire.One thing I can say about how well these work is that people don't ride up on my back tire anymore at stop lights! I use to have cars stopping within inches of my rear tire, but since this light bar has been installed, I don't think anyone has come closer to me than at least a full car-length... It really gets the attention of the driver behind you.Now, if you don't want the sequential light to function (or it is not legal in your state to have a sequential light in running-mode), you don't have to hook up that wire (the blue one)... its that simple...  Another option is to acquire a photo-resistor (pull one from a broken solar pathway marker light or buy one from electrical supply house), and place the photo-resistor inline with the blue wire.  The resistor will close the circuit when it is dark enough.  Now the sequential light only functions from twilight to early dawn, or on a really cloudy day / bad weather... when it is needed most, for extra visibility.
