Quality leds are designed to plug/play with factory housings without blinding anybody.
That's what their marketing/sales departments will tell you anyway.
Any plug and play LED headlight module installed in a housing designed for halogen bulbs will put light in places it's not supposed to be. They'll be brighter, but it's impossible to focus the light in the same way as a halogen bulb. I strongly recommend if anyone wants to run P&P LEDs in the composite housings that they do it in the high beams only.
The only proper way to run LED low beams in these trucks would be to use a W/T grille setup with the single 5"x7" headlights. Then you could use a set of housings that were designed for LEDs from the start, like these Trucklite 27450C for example.

IMO the best and brightest solution if you want to keep the composite style headlight housings is to upgrade the factory headlight harness wiring and run a good set of halogen bulbs in the low beams. If you want to take it a step farther, the Arteb composite housings that others have mentioned have a better reflector and lens design than what we got here in North America.
Trimming 9011/9012 HIR bulbs to fit 9005/9006 sockets is another good upgrade, but be aware that the factory 9006 low beam bulbs in these trucks have a painted bulb tip to reduce glare and the 9012 HIR does not. For that reason I would not recommend running a 9012 HIR as a low beam bulb unless you're running aftermarket housings that have a "glare cap" over the low beam bulb.
