Looking to add some blue LEDs to JBJ Nano Cube. Suggestions?

I'm looking to add a little more blue light to my JBJ Nano Cube intermediate, and I'd like to have the extra LEDs incorporated into the hood that came with the tank. I'm comfortable with rewiring things and soldering if needed. Does anyone have experience doing this, and if so, what did you need and how did you do it?

 

I got some stick on ones at my lfs. They were like $15 for three lights and they plug into each other and you can plug up to 12 in one power source and the power outlet was $12. This was more easy and cost effective for me. I got three. So that's nine lights total and under your hood there is a space infront of your lights behind the plastic you can stick them. They also come with a screw if you want them more secure but I went and got 3 m tape and they arnt going anywhere
