This is a pretty cool little device if you're looking to add internal and external temperature gauges to your car. The only two things I would recommend adding/changing are: 1) Insert a longer K-type cable. 1 foot is useless. I would recommend a cable of at least 2 meters. 2) It would be great if it could be connected to the indoor lighting wiring for dimming. The LED is nice and bright but I think it will shine brightly when driving at night.
