For anyone who does not have LED headlamps, Several companies are now selling LED H Series (7,9,11 etc) LED plug & play headlamp bulbs. I put a set from Oracle Lighting on my wife's commuter car and they are amazing. these came in a set of two but I noticed Cycle Gear has single bulbs, that are the exact same, as my Oracle ones for $69.95 each this week. They are 6000K, low draw and will make dramatic change in your lighting.
But on the subject of this thread, with the LED daymakers on my SERG I removed and sold the moto-lights and I had the ones with there LED's. They just did not add anything to the lighting, the Daymakers so totally overwhelmed them that I saw no need for them. The Custom Dynamics inserts match the HD Led's and all was good. I also, when I bought them, and still do think the Moto's are overpriced terribly and not as attractive or well shapped as the Headwinds, but they are brighter than the Headwinds, if the Headwinds guy would just move into the current century and get some brighter LED's then he would have a great product, I have a $80 Fenix pocket flashlight that puts out more light than either the Moto or Headwinds, and only uses one rechargeable 18650 battery so why can't the bike light people do the same.
