Looking at the bottom of the speedo you will see the wires that go into the unit. Those wires hold the bulbs that are just pushed into the speedo. To remove the bulb you pull the wires gently from the speedo then just gently pull the bulb out of the connector.
The color of the light such as high beam indicator and neutral is the color of the lens the light is shining through. The bulbs themselves are normal white light.
Stand by and I will get a pic of the bottom of the speedo.
These are the wires the bulbs go into. They just push in. (I know, I am showing more wires than there are spaces in the speedo. That is because the other wires are turn signal indicators and I do not use them because I have done away with the black plastic housing that houses the turn signal indicator area. I don't need it since my turn signals reflect rather well off of my head light bucket so I use that as my indicators. And my neutral light is still installed in my speedo so that is why you only see four wires in the pic.)
This is the bottom of the speedo. The large hole on top and the two holes on bottom are where the bulbs push into. The top hole is the main back light for the speedo face. The two bottom holes are neutral and high beam indicators.
