If it mounts an H4 style bulb, you can use your stock headlight wiring harness most likely. I used the stock harness on my 7" light.

 

On the tank lift you mention.
I used the same hose and yes !!!
It will affect the gauge a little but i never go to far out of town before checking fuel anyway.
Once you know where it reads after the change you will adjust..

 

I don't often venture here to the dyna section,but that single headlight on your Fat Bob looks killer.The dual headlights are the only thing I don't like about the Fat Bobs.Tough looking bike ya got there,Lorance!

 

Headlight uses H4 bulb so you can use OEM harness or cut and splice inside headlight (make sure your connections are good). Comes with a nice mount block but it's too short IMO. I used the stock mount with a thin washer on each side btw the ears as a spacer. Easy mod.

 

That light looks good on your bike.

One of the first impressions I had of the new Dynas with the 49 mm forks is that the 5.75" headlight looked too small. I put a 7" light on mine and now it looks right.

 

I really like how that looks. Thanks for the ordering information. This will be my next mod - I always thought the stock light on the FXDC was lost in the front end.

 

Thank you very much! I appreciate the compliment!
