They were very easy to install for me, but I have also done headlights before. I am no mechanic and just YouTube everything I do, and this was very simple and easy, plug and play basically. The drivers side requires a little more work, but especially with toyotas tou dont need more than a couple tools. Light quality and the curtain of the lights is very nice for aftermarket. Would recommend, also love the black insides of them. They look unique but they're far from that obnoxious after market loSee full review
