No, I mean (most) leds are polarized. Meaning they ONLY work one way. Try taking out the ones that aren't coming on, and turn the bulb the other way, so you will be swapping the (+) and (-) sides and try the bulbs again. That usually solves the problem.
I took my top two bulbs out. Gives the leds more contrast.
But good luck figuring that out, I hope you don't have to buy a new cluster, because they aren't cheap at all.
also, what did you use to paint your cutoff shield? did you just use high temp engine enamel?
