Oracle's 2007-2016 Jeep Wrangler LED Off Road Mirrors are a great addition to your vehicle to set it apart from the rest! Oracle Off Road Mirrors incorporate high powered LED light bars into the mirror housings, providing excellent peripheral illumination (bright light!). This is ideal for off road users (in addition to the great look they provide) because you'll be able to see clearly in areas to the sides of the vehicle that your headlights don't illuminate. If you've been trail driving or off roading, you know how helpful this will be! Oracle's LED off Road Mirrors are sold as a pair and feature superior CREE XPE 1W LEDs. Multiple heat sinks (aluminum) are used to keep heat away from the LEDs. Since they are LED, their power consumption is highly efficient (2amps). IP67 Waterproof rated means streams and serious off roading are no problem! The mirror housing is made from a polycarbonate and they bolt right up using your factory mounts. Anodized rock guards protect the LED acrylic lenses that house DBM Reflex LED Optics. Long story short, these mirrors are built to last and built to perform. Backed by a 2 year warranty. The part number for these Oracle LED Off Road Mirror Upgrades is 5751-001 and they fit 2007-2016 Jeep Wrangler models.
