DLR lights are not focussed so not blinding.
H4 LEDs use existing reflector.
Positioning of the LEDs is key to maintaining beam pattern. Hence recommended a supplier of LEDs.
You actually fit a carrier into H4 mount then fit LEDs into carrier. Only issue is to read instructions carefully as it is possible to fit LEDs inverted and this really screws up beam. Easily checked by marking beam pattern on inside of garage door then checking after replament with LEDs.
