Did a little DIY on the boat this past week. I basically did the same thing that was done here on this link on the malibucrew, I also use waterproof RGB Led lights, and also used 3/8 tubing instead. Turned out great for around 100$. Did 14 cup holders and got everything on Amazon except the tubing, was like 6$ for 25ft at Lowes.
Also instead of using 1/4 inch tubing to hold the rings together, I used 1/4 stainless tubing
The lights are super bright, the picture with them on are during the day.
