Good thing we're all trusting and gullible. Otherwise, these purveyors of cheap Chinese lighting products would go out of business. We sold aftermarket lighting like every other shop and they used Cree LED's. Assembled here from imported parts. I've even sourced out $850 HID's (per side!) for a long-haul trucker. Still had water ingress and problems within 2 years. Yeah, LED's may look good with their aluminum housings, stainless fasteners, beefy looking heat sinks, powder coated... lots to drool over. And I can't say there isn't an extremely well-made product on the market but there's a greater chance you'll get burned by one of the other 20 versions that don't stand up. Warranties are bullchip. Corrosion and premature failure are an almost certainty within a year or two. LED's are the fastest growing industry in China. Cheap to produce, high profit potential, and a huge market in North America (household, Xmas lights, automotive).
Caveat emptor. I'll stick with H6024LL's in the grill. KC's and aircraft landing lights if you need to light up the back roads.
