I have a 19 Premium and just recently installed fog lights. Great addition. Do know that they only work when the headlights are on, meaning they are not an independent light. You'll have to do some splicing and what not for that, nothing a YouTube video or 2 shouldn't show. I actually plan on doing that for mine today!My 2019 base impreza came out of the factory with no fog lights. How hard will it be to install fog lights on it? Do I need extra switches? Or do I need to cut a hole on the firewall etc?
