The bright LED light was initially introduced by a sheet metal worker, who spent some time as a guitar tech for a touring band. The guitar player (who shall remain nameless), had an issue with finding his pedals on stage, as his eyesight left much to be desired. More was left to be desired, as to his inability realize that he had a guitar tech to push the silly foot-pedals for him. ... Anyway...eventually, the guitar tech found a great solution. 'Make the light as bright as a runway marker', he said. 'He shall never lose it again'!
Someone realized the greatness of his development, and brought it to the world. He became very rich. Many manufacturers found this to be the best idea ever! The story soon becomes a sad one, as things turned bad for the guitar player. Suddenly, he became 'cross-eyed'. The bright light stressed his eyes so much, that he was unable to ever look 'straight' again. He was unable to ever play guitar again either.
The cross-eyed guitar player was left with nothing but a thermos, and a chair. And that was all he needed.
Hmm...this story sounds familiar...

I have an Eden bass preamp, with the same issue. I fixed it like this:
