First 3D project / shred light salvage

I am doing a design of a riser with a headlight inside I was inspired by fottaz design! 1528923541682 At first I wanted to use this little leds but I can’t source them for all my board I only have 1 1529006859499

So I decided to use the shred lights I have and I have never used My plan is to remove all the pcb except the led one and directly link them to 5v from my receiver IMG_20180623_185724 IMG_20180623_185731

What do you think? Any idea on what type of leds I could use, some RGB maybe? What type of pcb are those with the single led, maybe it exists with dual?
