Harley-Davidson 2014 Models use a Can-Bus System
(Harley calls it HD-LAN) which controls and monitors the headlight.
Kriss Can-Bus modulators are compatible but most other aren't on these new Harley models and cause the high beam to completely shut off.
Visit our headlight modulator pages and you'll find a link to an explanation about Can-Bus.
Kriss CAN-BUS modulators or "LED" modulators are designed specifically for the new Harley-Davidson motorcycles.
? If you're not sure if your motorcycle has an H4 type or LED bulb please give us a call so we can assist in making the correct purchase.
