They make micro arduino boards that have various pins that can be used for input and output. They are cheap also, like $10. But with some code you can program them to accept certain ranges and then trigger output pins which can light up LEDs.

Only thing you would need is a step-down voltage I/C as most of those boards are 5v. I'd recommend a one that puts out stable voltage regardless of input voltage which can fluctuate in a car, as these micro controller boards are pretty voltage sensitive. But those ICs are fairly cheap as well and those boards are low amperage.

That would be the most flexible option as then you can have different programs based on the sender OHM ranges, with the exact same hardware.

But those output pins could also be used to produce a different outout range. So you could use one to translate from one type of sender to another.
