Everyone notice the LED lighting at car part stores now?

Wow seems the new trend is LED lighting and lots of it. I was at a car parts shop and for $12.99 to $89.99 you can have strips of LEDs anywhere from 4" to 4' in all sorts of colors. Really bright. They even had a test button and little battery to see how bright they really are. Everything from single LED lights to light up a section of dash to ring lights to put around your headlight. I was actually quite surprised at the massive selection.

Before I run with any wild ideas I'd wnt to check here of course. All I want is running lights put into the interier indents of my headlight that run parallele with the hood. Those little dips are screaming to be lit up. Just not sure if this is the best way to do it.
