One of the more popular lighting mods has to be the use of neon. Personally it's not my thing but there are a lot of folks who love it. And there's no denying it gets your car noticed! The color choices and options are almost endless. From the traditional undercar neon tubes to color changing accent kits it's really up to you to decide how to use the neon. There are neon license plates, strobe lights, pedals sets, floor mats, shift knobs and much more. One cool spot for neon is under the seats. A good source for neon online is www.soundomain.com .
