pull the bulb out, spin it 180 degrees and push it back in. Leds are polarized meaning they have to be put in a certain way unlike the standard halogen bulbs.
I have this problem for the top of my speedometer and tachometer, but not nearly as pronounced... it's just dimmer than the rest of it. I use halogens because my LEDs burned out & didn't give light as well. Looks like you just need to replace them.
