Hello,

Just installed a set of 2018 J blade front lights (Auto Marc) on a 2014 XJL 5.0. I got the "plug in play with the AFS." The lights, signaling work fine except, dashboard warning light icon (with a smile/arrows) continues to blink. Called a dealer they indicated both may need a self-adjusting relay re: side lights. But these are LED lights. Any suggestions.

 

It doesn't sounds as though it's plug & play if it's causing issues with the AFS system.

 

It's not and no dealer will provide any help installing aftermarket equipment on your Jaguar.
There is nothing but trouble for any dealer that does this. It's all down side and no upside to them.

Why don't you follow our long running thread and update to the MUCH better 2016+ factory LED lights??
