I just installed sp1b and now im having issues with my lights. Neither wing, logo, or the anti collison lights are showing up on the 700 model. I have it powered up by the APU and the switches are on. Any ideas? I hope I'm just doing something wrong, but all the other lights (cockpit/taxi/landing) all function correctly, so I'm thinking it's a bug.

All working fine here - might want to consider clean installing.

Is that a clean install of the 6/700, or the whole NGx?

How are you starting the flight? Are you loading the NGX on top of another livery of the NGX? I had that issue when I tried to load the NGX while in a flight in the NGX (if that makes sense)

Steve's right actually - that will do it too. If you're switching liveries or variants you need to shut the sim down and restart it.
