<p>I like to run these lights day & night on my BMW S100XR & BMW K1300GT motorcycles. These reflective LED lights allow me to leave them on and not get complaints (flashes). </p><p>You can aim them so the light beam stops below a car's trunk lid. Of course, the LED Cube lights still fills out your profile and gives you that don't mess with me look. Whether its driving down a country road looking out for deer or splitting lanes and wanting that LED brightness to give the phone talking, chip munching, sleepy driver a heads-up.</p>
