They are a breeze to install. I've got them on the dime and on my 1200. I'd say about 95% plug and play. I had to shave the back of the housing mount points a bit to get the headlight rings to fit nicely. Otherwise, just pop them in and done. Wiring is plug and play. If you run halo's you'll need to find a power source for those. The light output is great, but my only complaint is they use a small projector in the housing which causes the beam to be a big narrow. To resolve this I just adjusted the lights to whatever the reverse of cross-eyed is. Double lazy eyed?
Cut off is nice, relay harness allows for highs and lows to be on with the high beams. Support is good. They are on the expensive side though.. wait for a sale perhaps.
