This is a Pair of flexible rubber boots for difficult fixtures. When installing a LED Headlight, the Black finned heat sink that sits of the back of the bulb should be in the open air so that it can cool. Some fixtures have the bulbs within, and plastic or rubber caps that cover the back of the fixture not allowing the heat sink to fit outside. These boots can help.
Soft flexible rubber. Can be install convex or concave depending on the application. Can be cut to size. Stepped bellow design allows different depths and widths. The boot inner flange goes between the mounting flange for the LED light and the heat sink. You can install them over the front, or on applicable LEDs, remove the heat sink, install the bulb and boot, then screw the heat sink back into place. Never turn on an LED without the heat sink in place. These are Universal Boots. They are not made for a specific application. We do not supply vehicle specific installation instructions. Altered boots are not returnable.
