Wondering what anyone's thoughts are on DIY LED lighting kits.  I found some pretty cheap ones I'm looking at putting on my car but I've never done this before.  How easy is it and how much of a hassle does anyone get from law enforcement if they have them?

These are the ones I'm looking at buying:

I may also be interested in interior ones as well.

Thanks in advance for any help!
