    A little time consuming but worth it
  

*by A***R on Reviewed in the United States on October 30, 2022*

It did take about 2 hours for my husband and father in law to install but it's perfect! I'm so happy with the results! I eventually put lights on the inside as well. I drive a 2013 white ford f-150. It doesn't really come with instructions so you need to know what you're doing or watch a YouTube video of this isn't your thing. The app is pretty easy to use. My interior and exterior lights use the same app so that's pretty cool. I did forget to shut them off one morning before I went into work and didn't realize they were still on when I hit home until that evening. Didn't drain my battery or nothing. They're LED so they don't use much battery anyways. I wash my truck roughly once a week or more depending on weather and they still work just fine. The color range and vibrancy is pretty spectacular. You can have the lights flash with your music, set them on different settings, make your own settings or just turn them to whatever color you want and have it glow that color the entire time. White is more of a rainbow color which I love. Lately I've had it on a pink/purple color. I also really like the light blue color but pretty sure it's illegal to drive around with blue or red lights (at least in iowa).

    Very Simple & Easy
  

*by R***R on Reviewed in the United States on January 29, 2023*

Used this for 18 rock lights on my truck and it’s super easy to install to an existing harness and good wire length to get into the cab. Just installed so cant give longevity review but so far it’s really nice
