im guessing its just a bulb, but this morning when i turned on my lights, half of my RPM gauge and temp gauge no longer light up..? can somone tell me how i'd change a cluster bulb or other things this may be?? thanks.

 

Its not the bulb, its the cluster fluid. Or maybe the bearings.

 

pull the cluster out, and replace the bulbs in the back of the cluster.
Its super super easy.

 

Cluster bearings are a bitch to replace. Make sure not to disconnect the hose to the fluid or it can become very messy!
