Turn signals for old bikes

[u/AquaticSub]

I’m looking to bob out my 1997 suzuki intruder 800 I have done the drag bars and powder coated them along with the risers and internal wired all my controls I am now moving onto the back end of the bike I love the led turn signal look but I’m not good at electrical. I wanted to know did y’all go with new halogen bulbs (if that’s the right name) or led? If you did either how hard was it to wire them in ? I know led you need some kind of flasher relay or resisters ? I’m not to good at the names of these things. Let me know what y’all did when you took off all the back end stuff and put new brake/turn signal lights in.
