As far as aftermarket signals go I have seen tons of different styles. Do they all match up to the front fairing without modification? Is there a good place to buy them or is Ebay the best bet? Any positive experiences from others (maybe with pics) would help!

 

Any LEDs i have ran into only have a positive and negative. The front of an F4 has three wires. They do make relays that you can put up front that will convert 3 wires into 2 which will keep your running lights and blinkers at a normal rate.. I usually buy most of my items off ebay. Good luck with your search

** The ones on my front i did not have to modify at all.

 

Whatever you get, just make darn sure it's easy to get replacement bulbs and ensure that they are approved for your location so that you can still pass inspection.
