Tail Light Issue
 

I have a '90 Integra LS, and i have a problem with my tail lights. My brake lights, signal lights, and reverse lights work. But at night my actual tail lights don't light up. Checked all the bulbs, all the fuses, and everythings good. I read a previous post similar to this and it said to change the Day Time Running Light Module, which I just did today, and there still not turning on at night. Do you guys have any suggestions? Thanks Alot.
