Missing cabin and logo lights FSX 737

[LANE]

I've just watched a BA 737-800 FSX on YouTube complete with cabin and logo lights. There was no reply to the posted question "How did you do it?"... so I was wondering if anyone has a clue how it was done?

The file I understand that needs to be there, is there (b737_800_1_L_M) as it is in the 747 which has all these lights working so what's the catch?

The cabin lights should show as long as they're on. The logo lights I don't know though. I've hit the logo light switch on the 737 before, but the logo lights never came on.
