b.borg, a valid question but as one who has flown the L, L2 and 225 I am unable to answer. There are of course many differences between each variant's lights and procedures, but what in particular they are alluding to I don't know. The L2 for example is the only one with the rather odd pendulous balance weights on the main rotor blades, but it would be pure and unfounded speculation to say that this might be the issue. If it was, I'm sure there would be an EAD out by now.
