If that doesn't convince you, here's something a little closer to the (Toyota) home:

Why LEDs should not be run in Halogen reflectors | Tacoma World

I've been experimenting with improved lighting on vehicles since I bought my very first new car - a 1976 Toyota Corolla SR5 Liftback. I can't tell you how many different lights, bulbs, harnesses and other stuff I've tried over the years. LED bulbs are just the latest fad and although some of them are barely passable, most of them are just junk. (BeamTech and Auxbeam are just a few of the poorest.)

The excessive glare issue has been somewhat solved by a few of the better manufacturers as of late. The cheap stuff still has this problem. Funny thing though. People who bought these cheap bulbs used to stand in front of their vehicle and take pictures to show "how bright" their new bulbs were. What they were actually showing was how much more glare they had installed.

The new problem that has been created is excessive foreground light. The better manufacturers have dramatically reduced glare by directing light downward. Most users don't see this as a problem though because they say "Look at how much light is in front of my vehicle and nobody flashes me." What they don't realize is that they have lost almost all distance projection. Is that bad? Not if you don't mind cruising straight into the deer standing in the road just out of your new headlight bulb's range.

If you want my 2 cents, although the better drop in LED bulbs are better than the cheap junk, they're not actually better than a good halogen bulb. Oh, and they're still illegal. No reputable manufacturer will sell you a set.
