    I have a customer that I installed some gauges in there F250, he has red LED lights under the cowl hood that can be seen when inside the truck. He wanted to know if it was possible to have these light glow dim or off at low boost (under 5psi) and glow bright at around 20 to 25psi of boost, so the lights would follow the boost pressure.

    I am not sure if someone makes a sensor that can be installed inline with the boost gauge that can work these lights that way.

    Any help or ideas would be appreciated, I told him I would look into it but didn't commit to anything.
