Unfortunately, yep, really.
But like I said, this depends highly on your local area - and the areas which you travel through most often, too, of-course. What may constitute a "one eye open, one eye closed" kind of thing, as us Chinese would say, in one municipality may well earn you either an interview or a "fix-it-ticket" in another, so it's good to get a feel for your immediate locals' enforcement values/prejudices, as well as that of your most often frequented areas'.
.com isn't without tales of people with LED plate illumination that's run into trouble - but again, it's all dependent on subjectives.
And just look at what happened recently in Maryland:
Maryland Judge Decrees Pontiac G8 GT Tail Lights Illegal
^ I mean, that's just a plain really! scenario...but what can you do? At-roadside, it's virtually impossible - and in most cases likely highly counterproductive - to debate the stop or the citation, and even if you were successful in doing so, that's still time that you'd never get back. And you can only pray that, in-court, at least the judge wouldn't be so careless, ignorant, or as stubborn as the one that particular enthusiast encountered.
Locally, things have gotten much better in the last 5 years, but during 2001 through 2004, it was really rough - many people, regular, everyday folks who were respectable appearing enough: post-grad students, doctors, professors, etc., were getting pulled-over and either interviewed or cited for failing "red-by-sight" laws on their new and unmodified Lexus and Acura vehicles. One particular classmate of mine received two tickets within the span of as many months, from two adjacent but separate municipalities (granted, in many of these cases, particularly back in late '01 through early '03, a lot of the individuals targeted were darker-skinned individuals who were apparently not of African-American ethnicity). The kicker? Ohio has no "red-by-sight" laws.
The reason why I'm so cautious about things like this is because in my area, a little paranoia does save a lot of headaches. :smile:
Now, I don't want you to be paranoid, bro - that's not the idea, here. :wink:
Instead, it's to just make you aware that such concerns are real and do exist, and that as someone who drives an obviously modified import vehicle - even one that appears as family-oriented as ours - this is something to still think a little about.
