I see no difference in Highlight adjustment between the first post and post #23. If that is the case red light was completely blown but it is hard to tell from the small picture. The only thing I would do without sacrificing the rest of the picture shooting 5 stops underexposed is to shoot again using 4 fps. The red light in some frames would have less intensity, less glow at start and finish. Looks like you caught it at the peak of the cycle.
