The "Red Tail" series of LED bulbs utilize a braided cobber cable for heat dissipation, there is no fan that can fail, and less radio interference.
We recommend using this bulb type in areas with no airflow, for example - lights that are built into a combine cab.
Replace your halogen or HID bulb with LED High power bulbs. Enjoy low power draw, great white light with less blue rays than HID, cuts thru dust better than HID and Halogen.
There is 2 bulbs in a kit.
