[QUOTE="FJRGlenn, post: 617296, member: 6700"] Great to hear that all worked out. Our lights will fully regulate current (and brightness) at any voltage over 12.2-12.4. If they see less than that, the controller cannot adequately manage the brightness and hence the flicker. For some reason, you bikes alternator is not producing a charging voltage at idle. This could be due to the heavy current draw from your upgraded HID lights. When Yamaha updated the alternator on the new bikes, they increased the alternator output. But, most manufacturers rate their alternator output at an elevated RPM, such as 2000 or 3000 RPM. This is a more realistic minimum operating range. (ok...let the jokes begin.....) Just because an alternator has had its output increased, that does not mean that output at idle is increased. It could actually be lower. The way the alternators internal wiring is wound is what imparts a change in the charge/RPM curve. Simply turning up the idle 100 RPM or so may just be the solution needed.
