For Jeep Grand Cherokee 2005 2006 2007-2010 LED Headlight+Fog Light 6× Bulbs Kit

How to choose the correct size? 1. To confirm the size in your original user manual or by checking the original bulb's back. 2. To search in web with “automotive bulb look-up “and find out the bulb size. 3. Contact customer service to check the vehicle model. Plug&Play Quick Installation. Built with smaller size than the common LEDs in the market without building an external driver, directly plug into the factory housing. Neither side lighting up? Both sides flicker, flash, or work inconsistently. Check the headlight fuses, and then check the ballast plugs to insure correct installation. If this doesn't work, there may be a voltage problem with the vehicle. You probably just need a relay or capacitor.
