I bought the shell in july of 2018 and rb swapped it. I just recently got it on the road and have only drove it at night once or twice. I did the relay mod on the headlights during the swap and they were working fine. A few days ago I was checking everything over because there is a local car show weekend coming up. That's when I noticed this problem manifested. I pulled my turn signal switch to clean it out because about half the time they weren't working. I got those fixed and put it back on the car and then the headlights weren't working. I pulled the headlight switch before I left the house. I'll get some pics of it with I get home.
