Headlight questions. aftermarket
 

I'm sure this issue was already covered, but I'm having a hard time finding an exact answer to a question.

I know there are HID kits that work for the 2015 200 S (without premium lighting package)

I'm looking at probably getting LED replacement kits for headlight and fog. Is the issue the same with LED as with HID?

I read people are having problems with it not detecting not turning on, having check engine light come on.

So what's the issue with LED? And what kits works?


Thank you for any input you have.
