Review on 🔦 DZG D1S D1R D3S D3R D8S LED Headlight Bulbs: 50W 11000 Lumens 6000K Bright White - 2 Pack Conversion Kit by Ken Coste

I decided to bring this back for a number of reasons. First, because they would require more hacking into my Mercedes system than I would like. To install them, you need to find the ballast in the car, disconnect and reconnect it. You may need to drill a hole for the wire to exit the case if the ballast is not in the same location. Second, my HID kit with projectors that can pan left, right, up and down is a very expensive option and I decided it would be best not to bother with an aftermarket upgrade. The last reason I brought them back was that I had watched many videos and read posts with photos of the light output and radiation patterns of such modified LEDs and this study raised some concerns. In a video test of several LED lamps on YouTube, they measured half the light output compared to conventional HID lamps in the same projector housing.
