The "Red Tail" series of LED bulbs utilize a braided cobber cable for heat dissipation, there is no fan that can fail, and no radio interference.
We just now had a customer that got 9 bulbs replaced and have radio interference - but when tested here (1 bulb) we did not have any interference. So we now only recommend using 2 kits (4 bulbs) on a vehicle.
We recommend using this bulb type in areas with no airflow, 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 are 2 bulbs in a kit. This bulb type requires 3-4" of space behind the light for the cooling system to fit.
