Because both the "hot" and the "oil" dash lights have been discontinued years ago, we came out with our replacement warning lamps. There are a few advantages to our lamps though vs the OEM lights. First our lamps sit on top of the dash, so in the daylight you can see them if one comes on. The OEM lamps were in the dash and in the daylight were very hard to see if one came on especially when over the years, the Sun fades everything. Another advantage is you can inspect and replace the bulbs to make sure they are in working order where the originals were not servicable. Our Red lens unscrews to reveal the bulb. These are also color coded to the OEM harness. Yellow is the "HOT" light, and Red is the "OIL" light. They plug right in! Just another addition to the 616-720 Tractors offered from us at B&B Custom Circuits. Don't guess! Go with the best! B&B Custom Circuits products!
