I bought mine from Zanotti for a lot less than the $399 list price. Installation on my 2010 FXD was a 5 minute affair, easy job to do (it'll be embarrassing to have to pay someone to do this job it's so easy). The process to aim the light properly takes more time and some trial and error. It's still a very simple job to do. Once everything is dialed in, you get a very nice even spread of bright white light in both low and high beams. It spreads nicely to the sides and projects far enough in front with a very well defined pattern (think of a bowl viewed from the side). My stock headlight gets drowned out by oncoming traffic lights but this LED light overcomes that problem very well. The LED is a nice upgrade for those that like to keep things simple and not change the look of their bike with auxiliary lights, Motolights, crash bar with foglights or Kuryakyn frame mounted lights. Riding at night is made much safer with these lights. Highly recommended.
