If there is not a color issue then tell me why your temperature needle is showing ? Company had those conventional bulbs in the meter. its the green or red transparent part on the cluster plate which gives the green or red light. these colored bulbs are not that bright to give enough light. if you see your temperature red needle is visible.
Your RPM needle is invisible. Your speedometer, the red light is struggle to bright your speedometer needle. and the same with the fuel needle. blue light is struggling to give enough brightness to the fuel needle to make it visible. Zoom in and see it.
Look at @xenerking bhai's car meter. HOw neat is it looking MA.
Hope you understand it. When you open your cluster meter, dont fix it back before checking the visibility of your car meter. ONce you satisfy then fix it properly.
