So I got tired of the very dim green dash and gauge lights for my 280z. I didnt see anyone on the forums so far doing this yet so I decided to take a crack at it.
Gonna try and make this easy to follow and understand.

If you too are tired of having to squint in at your gauges when driving at night, then you might want to also consider this.
Just some basic info:
Most production cars use wedge type bulbs for gauge lights that twist out of the back of the gauge. These wedge bulbs also usually have a type of plastic coating on the tips that is Green/Blue so that when installed and turned on they give off the color they are coated with. Like green or blue as described.
Our Z cars use a different setup (atleast the 240z-280z). These Z cars use an older system of bayonet style bulbs that you push in and twist to lock in place. And instead of the bulbs having a coating on them to give off a certain color, the gauges themselves have clear plastic domes fitted into them that filter the light. In our cases the Standard Green.
When the dome filters the light its also cutting its lumen count down also. Which means its not as bright.
