Here are my headlights from when I did the LCI headlight retrofit. You will see the two LED modules with the heat sinks. I find it hard to believe that they both failed at the same time. There is a common power wire to them, so that is where I would check first.
Check WDS for the exact pin on the harness, and then use a meter to verify power. You will need to remove the wheel and the fender liner to access the harness plug easily
