Hey People I have a 2013 SRT8 Jeep Grand Cherokee, when the engine is not running the Parker lights (Headlight Ribbons & Tail lights work fine independently) when the engine is running they will only go if the Fog light are switched on. (This means if the Jeep is stationary with the engine running the Parker Light Ribbons, Tails light and interior instrument lights will only go if the FOG lights are on! This does not seem normal to me. Can anyone tell me if they are able to use their Parker lights when the engine is running with out the need for the fog lights or headlights switched on please???????
