I've been searching everywhere about this. I know a lot of people that have too, but not a lot of people have the answers. I found this posted in a streetglow message board:

To Whom It May Concern: I belong to an online community in which automotive
enthusiasts referred to as GÇ£GLOWERSGÇ¥ (in reference to using automotive neon
light rods in, on and under cars) gather to discuss and debate topics that
range from customizing cars to legal issues involving automotive neon
lighting. With automotive neon becoming increasingly popular, one of the most
debated topics is GÇ£legal issues regarding the usage of undercarriage neon
lights.GÇ¥ I have come across several websites and related literature
concerning the laws of automotive lighting. From all of my web-based
research, I have found the following to be most interesting:GÇ£There have been
many questions regarding the legality of (neon) products. Please be advised
that many states have issued Summonses, under the statute of improper
lighting, optional lighting, unapproved lighting, or improper use of
lighting. However, these statutes are primarily focused on original vehicle
lightning which must abide by certain rules and regulations set by AAMVA
(American Association of Motor Vehicle Administrators) such as, ONLY red,
white or amber are allowed on a vehicle and these lights must be no brighter
than a specific brightness allowed by law, and the lights must be affixed at
certain heights. Under these terms, if NEON that is installed beneath your
vehicle emitted just a glow and the bulb is not visible from the front, rear
or sides, regardless of color, IT IS 100% LEGAL!You have every right to have
neon lighting because there is no law, in ANY state that prohibits neon
lighting.GÇ¥
(http://www.autotoys.com/New_Tech/Mis.../neon_laws.htm)My
question to you is as follows: If neon light rods are installed beneath the
vehicle, in a manner in which the bulb is not visible, but still emits a
GÇ£glowingGÇ¥ effect directly underneath the chassis of the vehicle, does this
make the usage of neon lights legal?I, as well as everyone else in the online
GÇ£GLOWERSGÇ¥ community, would greatly appreciate an explanation as to whether
or not the usage of automotive undercarriage neon is permitted. If
undercarriage neon is not legal, please include an explanation as to why it
is not. Also, please include in your explanation where and when automotive
neon can be properly displayed (i.e.: While vehicle is parked, In parking
lots, etc). I am just one of the hundreds-of-thousands of people in search of
ways to legally defend the usage of undercarriage neon, and would really like
to bring back some concrete answers from the people that enforce the
laws.Thank you for your time and input regarding this matter,
