Review on NORDLICHTER H7 LED Bulb, 10000LM Fanless, Ultra Bright 6500K Cool White Conversion Kit - Pack of 2 (Halogen Replacement) by Todd Raynie

They are much brighter than the Hella halogen bulbs I had. I believe they sell adapters for this, but as far as Revain claims they will fit my car, they don't. etc. You can make a standard MB holder but you will need to use a dremel to increase the size of the holder where the frame goes. Then remove the o-ring and use the channel fasteners to bend the connectors into place to fit. It took me 1 hour of work to figure it out and I didn't have to do anything permanent and I can still use halogen bulbs if needed. Hope that helps. To edit. Do not use them on a Mercedes with a projector. You can't see as far as you can with halogens, even though they look brighter. The front is light, which is the opposite of what you want. High beam with reflector is also not good. Leaves black spots. However, they work better as low beams. Halogen was even better. The LEDs were aligned correctly and I tried a different orientation. The problem is that the lamp has only 2 LEDs and half of the reflective surface is not working. For fog lights they should be good. However, here in the rust belt, fog lights should be used 3 days a year. Fog lights should not be used in everyday life as they make the front of the car very bright and your eyes don't see that well. Only use the low/high beams if you want to see the deer sooner. To edit. I returned them and bought hickory leds and they work in either position.
