Ohh that argument is really old now snow. Sure in the old days (years ago) LEDs were terrible in housings but they have come a LONG way. The kits we sell do NOT blind drivers (otherwise we would not sell them, as we don't sell anything that is crap and causes problems... one reason we don't sell those cheap RGB light bars the Jeep guys love). Sure there are still some cheap crappy kits out there that do more harm them good (TONS Of them all over).
We've always offered folks their money back if they have problems and cause glare. So far... not one person has taken us up on that or reported any glare. In fact... I used to get into arguments with guys who were VERY anti-LED until they tried our lights and they started singing a different tune afterwards.
