Sissy bar lights
I got this exact one and installed it on the OL's FXDL. It's plug and play. You do have to pull three pins out of the rear light connector, and plug in three new pins, and transfer the pulled pins into the new connector, and do some ty-wrapping of the new wiring, but it's no big deal. The connectors are AMP multi-locks, so you have to have the tool to extract the pins, but if you have the service manual (and you should) it shows you exactly where to insert a safety pin into the lock to release the pins. Made a big difference at night. The more light the better...
