I'm working on a LED tail light and signals myself at the moment. Being a truck driver I tend to get into a little "trouble" mixing and matching things, but I'll be using a 4" red sealed tail/stop LED light with a quick disconnect pigtail spliced into the factory harness, the mount will be similar to most other cafe seats, in the hump. For turn signals, I've yet to decide, but you could look around on iowa80.com or other truck driver chrome shop sites. just my .02, good luck
