DELTA 3088 Series is a waterproof adjustable 3.5" Fascia Fog Light. This version of the light is designed to fit JEEP JK or JL with plastic bumper. This light is a direct retrofit replacement of under-powered factory JEEP fog lights. These DELTA OEM lights feature optically engineered light distribution with a vertically adjustable reflector to allow for a variable angle adjustment. This allows for perfect aiming regardless of the vehicles ride height. The IP65 waterproof design also has a one-way air valve. They are SAE and ECE compliant. This light uses H11 bulbs or LED system for easy plug-n-play replacement of the OEM factory fog lights. From 2007-2011 JK used H11, the included plug type. From 2011-present Jeep switched the plugs, an adapter is included for these models. In most cases these fog lights will provide more light power than your headlights.
