2017 GLC LED bulb replacement

Anyone know of a good aftermarket manufacturer for LED bulbs for a 2017 GLC? It takes H7s but im unsure of which ones to get. Also do I have to buy 4? As the low and high beam are 2 different bulbs. Will they function the same?

Thanks

What is the difference in performance between LEDs and HID? Is there a recommended HID setup for that vehicle? How come its better in a halogen housing?

Thank you for your response

Thank you for your response

Halogen housing is designed to capture and project 360 light output bulbs spread. With LEDs, you have point dispersion light spread that will result in reduced throw distance, light scatter, and dark spots. Granted they can still be better than halogen from brute force lumen output, but HIDs will out perform as the housing can make better use of HID 360 light spread it is similar to halogens.

This is the kit we'd recommend Hybrid H7 HID canbus conversion kit. We assembled this kit with the assistance of the MBWorld M/G(x) class forum community as a best fit and function kit for your particular SAM controller.
