First thing I'll say, these are only plug and play based on your idea of what plug and play means. I took plug and play to mean that with no knowledge base of how to install headlights on a motorcycle, I could do this by unscrewing some screws, unplugging OEM headlights, plugging in these headlights, re-inserting the screws and presto! Done. That is not the case. Less than 5% of the entire install process is plug and play. My install process required the removal of a majority of the front end parts of my bike, including fairings. As it turned out, one of the wires was too short to reach it's connection point. This meant lengthening the wire. So that entailed stripping and soldering the wire to make it longer. Then of course you have to seal and then heat proof it. Not that big of a deal, unless you were expecting plug and play. I was expecting the process to take less than an hour. Instead, it took about 3hrs. Now, full disclosure, mine was done by professionals with over 20yrs experience (even they say this isn't plug and play and this is what they do for a living). I watched the entire process. I am still amazed that this is considered plug and play. I never would've been able to do this on my own. Perhaps it's possible that the wire that required lengthening was an anomaly specific to my kit. Once you get past the disassembling, soldering, sealing and heat proofing, then the next few steps are plug and play. Then you have to tap into the turn signal circuitry to get them to work properly (not plug and play). Fitment is excellent though. Except that 1 wire, all other points fit and align perfectly.Once these are installed, they look GREAT! They are bright, clean and definitely give your bike a different look from stock. I find the low beams to plenty bright. I find the high beams to be extremely bright. Even the running lights are plenty bright. I will say that one persons idea of bright may not be the same as someone else's idea of bright. No matter what your idea of bright is, these are most certainly brighter than OEM.Finally, if you are comfortable tinkering, disassembling, wiring, soldering, then this may be a good little project for you. None of it is necessarily hard, just outside of my wheelhouse and exceeds my idea of plug and play. I would suggest a professional installation unless tinkering with motorcycles is your jam. I still give it 5 stars cuz they look and operate sensationally. They arrived on time and had all the parts it said it would have. Get the relay (sold separately) and install it. The relay was plug and play. It took less than a minute.

Sweet! Look great. Mostly plug and play, but you do have to splice the turn signals.

When I opened the box and removed the packaging, the power bank on the back was already broken. While attempting to put in the light fixture, the second power bank broke. Once when I figured it out it wasn’t too hard to install. They look nice and I like the low function setting

This light not only is twice as bright as the factory light but has the best daytime running lights. Easy to install and fabulous

Just over a year and these headlights aren't working. They were pretty good when they were working but if they last just over a year, not a good buy.

Love it. Works perfect, super bright and have tested at night time and I do think it's a lot brighter than stock. But the look is where it is awesome. Definitely a must upgrade if your wanting to stand out from a basic ninja look or any other sport bike.

Bolts up like the oem set. Wirings something to look at, Id rather not as something to the handles that can be avoided

Perfect OEM replacement and way brighter too. Also gives the bike way more character!
