LED kits

Has anyone in here installed a neon/LED underbody light kit. What is the difficulty level.

I'm not big on underbody kits, looks a little too fast and the furious! They work off a 12V switch and use a converter to power the neon lights. You can hook them in directly through your battery or it is better to route them through a switch, this way you can control when you want them on and when you want them off...there is no sense in running them during the day.

yeah, its the second time u post this right. i said the same thing, i dont like them too much, but i have seen 2 mustangs with them that did look good. and anyways, as long as u like how it looks, thats cool. u could prolly do it by urself
