I am in this site http://www.oznium.com/led-flex-strips and the longest length besides 6 ft is 38". So thats not that long but do you think that is good enough? Or does anyone else know any other site that has LED's for under the car?

 

i'm pretty sure on that site somewhere it recommends a length..probably the 6 foot. I mean, the distance between the front and back tires is definately less than 6 feet.
like i said though, i think it's in the section of Flexible LED's that it says something like "get the "x" length for total car length" or something like that
