How to differentiate between halogens and factory xenons for upgrade?
I have a w208 Cabriolet. I just bought some new aftermarket headlights (Sonar) based on input from people on this board. I had already bought Depos for my BMW in the past and were not too happy so I decided to go with a different brand

If I do have Xenons, will these be plug and play?

thanks,


Dennis

Took some pictures this morning, one of the plugs fit and one does not. I guess that means mine are Xenons

 

here is a picture of the plugin on the back of my new halo lights and in the lower left is the plug from my original headlights. Info on how to remedy this from someone who has encountered it would be appreciated.

Thanks,

Dennis
