these are all super bright 12" neons from street glow. these are great.

 

As far as ease of install is concerned, if you've never had experience with it before, Randode interior lighting makes it really easy. Randode has everything all mapped out and instructions for the tC specifically included. Also its already all ready to go when you receive it so its literally plug and play. The full interior kit includes 4 cathodes, 2 for under dash and 2 for under the seats, the transformers, an OEM rocker switch, all the wiring, etc. It was $80 when I got it and they are very bright and a lot of my friends with similar kits notice that it is the brightest out of them all.
