I had the GTS taillight covers on my '96 Accord Sedan for about 5 years. I live in Florida, and I never once got pulled over because of them. I even drove without a license for a little while, and didn't get into any trouble.
FWIW, I think AVS makes slightly higher quality blackouts, but the GTS ones looked and fit fine. I used nail polish remover to take off the silver GTS logos.
edit: yeah I know there's sun damage on the back bumper. That poor car lived outside.
