1st of all even though it states 91-05 Dynas, it does indeed fit into my stock 09 FXDC bucket without any problems. The light demonstrates great light beam pattern with natural daylight color. Unit is very solid versus the OEM plastic halogen light with a silver painted plastic reflector inside. I did call the supplier - JWSpeaker. They confirmed that they make the light for HD and are not allowed to sell the 5 3/4" light as HD has the exclusive contract. They also stated that they adhere to the same parts and quality in that light as in their other LED lights. In other words, HD did not tell them to skimp to save money. Instructions does state it has less draw - 3.75 A versus OE 5-6 A. Very pleased so far. Pics below.

 

Would you be able to post halogen vs. LED headlight pics?

 

So what does the beam pattern look like? Is there a sharp cutoff or is there plenty of spillage to light up the surrounding area?

 

I just got teh ones for the Ultra will have to wait and rebuild funds for the Dyna, thanks for confirming fitment. I think tthe stock is a very weak light. I plan to send the stock housing out to get chromed then plug this bulb in add 1 inch extension to push light out. Do you forsee any fitment issues with the brow visor ring?

 

on harleys website if you look up the led headlamp they have a video if you click on picture big difference between stock and led cool stuff

 

where did you pic this up?
