Neon?
 

i was wondering if anyone has heard of those HOTWirez made by streetglow and if they could be made to work on a x mods as a undercar kit..........I think it might.... Ill try it out onnly if i find out how much power it drains

Well they come in three, five, ten, and fifteen-foot kits from $19.99 to $69.99 (according to StreetGlow). Says there that they run on 'low voltage,' but that means something totally different for a full-scale car. They look like they'd make great underbodies, since you can cut them to any length once you get them.

Might just do that. :D

Ok, I just found out that they use 2 AAs, which equates to three volts. I don't know if I can fit another two AAs under the body, it'd be screamingly tight at the very best.

maybe just running it of the car batts...................that probably cause too much of a drain.....i just looked and 2 AAA put of 3 volts im sure you can fit those

You also need a large driver box (circuit board) to run the wire... wich is bigger than 4AAA :) .. they typicaly run off of a 9volt... good luck fitting all that under the body...

Well the Power Paks use 2 AAs. The other ones require a 12 volt power source.

And dont they also require an inverter or transformer or something? good luck fitting that under there..
