Hello,

I had the idea on going blue for the jewel light, but when I installed it, I´ve noticed that the amps led itself was red, and it overtakes the blue jewel, so I wonder where I can find a blue or white replacement for that ?

Thanks!

Color light LEDs are now common. You just have to buy a couple on on-line-component seller. But the issue you will have is the Vf of White is 3.5V, blue is between 2.5 to 2.8V and red is rougly 2V. Then you have to adapt it to respect SOA (safe operation area = max power) 8)
