This issue is very easy to solve, even at a small cost. If your car's taillights suddenly go out, don't go to an electrician! If it's just a matter of replacing a light bulb or fuse, you'll be fine on your own, costing only a fraction of the repair cost at the shop. You could get fined when you drive around with faulty lights, so don't delay. Try looking for new lights in online stores or auto parts dealer forums. When I was looking for headlights for my car, I also found a smart socket https://www.amazon.com/smart-plug-wifi-plugs-alexa/dp/B09KTYH3MJ. It's a good thing we live in the age of the thriving Internet.
