By lights, do you mean like how cars have them under it?
If so, I'm pretty sure it would be safe to say you're all alone with that idea.
When it comes to lighting like that, I think the general consensus is similar to that of cars.....
Cars that have them = Rice
Bikes that have them = Rice
I've seen them on bikes but they certainly don't fit the exotic bike category. ALL of the ones I've seen have been on Japanese bikes and are usually decorated with chrome wheels and/or a stetched swingarm. Great for bike nights....Not really. No thanks.
i've always said no but every time i see a bike nicely done, i say yes. so i dunno. depends. if you go moderate and don't overdo it and the lights are in the right place, i can see "turning them on" late at night while cruising in the city.
don't even get me started on how much I hate harley davidson dealers , led's , spinners, flames, those tassels people put on bar ends, ape hangers, faux hawks on the helmet
barf.
