Thank you for viewing. This is an Autogauge water temperature gauge. It was working fine until I removed it, but I'm selling it because I bought a new one. When the LED is emitting white light, there's a dim area, but there's no problem when it emits orange light. I think there's no problem if you use it with orange light, but I'm selling it as junk, considering that it might need repair or be used for parts. It's a 458 series with an angel ring. The size is 60φ. There are no sensors, and everything in the photos is included. Since it's a junk item, no returns or refunds are accepted. Please refrain from purchasing if you are overly concerned about the condition. I will not lower the price, so if you want to buy it at a lower price, please look elsewhere. Thank you.
