I had no trouble finding details. I did a web search and typed in 2019 rogue led headlights and three how-to videos popped up. XenonPro offers High, Low, and Fog LED bulbs.
1) This seems to be a common complaint with these kind of LED bulbs.
I have a 2019 Nissan Rogue. The H11 fit easily in the low beam socket.. The Hi beam seems to be a totally different story.. There's a large plastic protective case covering the bulb that may or may not come off without a hassle. I've seen videos of one guy that broke them and then used duct tape to cover it from the elements.. After that it's up to you what you want to dissconnect to try to make it easier to install. Unless you have a 10 year old's hand and an adult length arm it's no fun to change. Low beama are a snep.. Hi beams ? I've delayed installing mine due to viewing that video..
