i think underbody lights are played out and out of style at least in my area i haven't seen a car w/ underbody in over a year. show cars still have them at shows but no distinguished cars on the street have them here.
if you are going to go with underbody lighting, DO NOT GO WITH NEON... you shouldnt even go with neon on the interior. neon fades out over time and loses its brightness... go with LED, all the way. i have a blue LED underbody kit on my yukon... it has (2) 54" tubes and (2) 48" tubes but they are not hard plastic tubes like normal neon.. the LED bulbs are surrounded in rubber for a total of a 1" thick tube, making them water resistant, chip resistant, shock resistant, etc. i have had this kit for almost 2 years now and have not had ANY problems with it... but ALWAYS go with LED bc they last A LOT longer than neon, never lose their brightness and are fairly cheaper... go check out ebay, u can get all ur LED needs for cheap. hope this helps. l8r (ill post a pic of my underbody soon and my interior so u can see some LED) l8r
I have red LED underbodys made by a company called Lite-Glow and im pretty pleased with them. just my 2 cents. they were like 69 bucks on ebay shipped. but then again.. u get what u pay for just like everything else.
