Don't mess with these "LED conversions" if you want you and your car to live. They are a scam/fraudulent product, not even remotely capable of producing even a minimally adequate, safe amount of light in an appropriate beam distribution. It does not matter whose name is used (fraudulently; "Cree", etc. -- Cree does not make these, nor does any other reputable maker) or the particulars of the (bogus) claims made. They do not (cannot) even come close to putting out enough light in the right pattern to light your way safely. If you install these (whether in cheap and nasty headlite-shaped toys from India or China or in good quality legit headlamps) please—I am being serious here—
DO NOT DRIVE AT NIGHT. You may think they're nice, but we humans are lousy at accurately(!) judging how well we can really see; it's just the way we're built, so "Well, I like them and I think they're great" just isn't good enough. As far as safety performance goes, if it's a choice between cruddy old sealed beams and these "LED conversion" kits, the sealed beams win with both hands tied behind their backs and a big ol' wodge of duct tape across the lens.
There's a growing number of (real) LED 7" round headlamp assemblies available on the market. Quality and performance range from pathetic to excellent. If you have the money to spend $200 to $500 per headlamp, you can get really excellent nighttime seeing with life-of-an-A-body durability and lower current draw.
Peterson's 701C (also sold by KC HiLites) and
Truck-Lite's (also sold by GE) are two very good American-made LED 7" round headlamps. The king daddy of them all is the compound-projector
unit from J.W. Speaker, also made in America.
(Also, no, it ain't necessarily true that "DOT lighting laws suck". There's too much room in both the US and the international European regs for bad lights, but there's also plenty of room in both standards for excellent lights.)
