I like it much more without hthe lights. The design without the lights looks more real, like something we can see on shelves in 50 years. The lights look too superflourous, like they're there only to make the design look more sci-fi-esque.
If I was walking through a parking lot at night and saw the 1st version without the lights, I would be very creeped out and unsettled. Now, If I saw the version with the lights, I would think to myself "Huh, that thing must be for some kind of promotional stunt or something."
The lights pull away the attention from the robots disturbingly human face and make us look at places far less powerful. Removing the lights puts the focus right back on the robot's eyes, the most memorable feature on the design.
