It'll fit and work. But you may experience a hyper flash due to the bike's computer thinking the bulb has blown due to such a low amp draw with the LED.

Yup. They're usually a pretty easy plug & play. I use Custom Dynamics.

that's for turn signals, not brake light, correct??

I put 1157 LED in my brake light.
No problems I've noted

..L.T.A.

I've always used a load balancer right away so I've never had any trouble. But I guess it makes sense that the brake light would be OK because it doesn't auto flash.

Give CD a call, see what they have to say. They're pretty much straight up with answers.
My understanding is you will need a current limiting resistor.

You can use an LED for the taillight without needing a load equalizer. You will need the equalizer if you change out the turn signal bulbs for LEDs on a 2010 Fat Boy Lo.

While an LED bulb will generally be brighter than the stock incandescent bulb, you can also replace your taillight with one of our LED assemblies -- these will be significantly brighter. You can see the taillights we have for your specific bike here: https://www.customdynamics.com/amfin...sid=1NtIpxDCMp
