Okay, today on the way home from work I got pulled over twice for no tail lights. I was lucky to get off with a warning both times, but I do not want to be driving unsafely, yet I need to get to/from work on a regular basis, sometimes into the darkness. Anyways, what is a comprehensive list of what I can check as to why they are not working? As added information, my brake lights turn on, but not my tail lights. I have about 30 hours between shifts here, so anything that can be done, I need the info to get it done soon, so thanks in advance for any/all assistance you can offer!
