How’s the LED headlights and fogs that come on the LT trim silverados?  I had 2 previous gen sierras with the projector lights that were horrible.  Are the 2019 Silverado LEDs better?

Yes. These are excellent. Maybe too good, I do get flashed once in awhile.

One cannot overstate how excellent the LED headlights are on the T1 trucks equipped with them, IMO.

That's because putting an LED in a projector housing is like painting black stripes on a white horse to make it a zebra!  We have different animals here.

 

That was my MAIN reason why I traded my cherry '16 with projectors for a '19 with LEDs.....too many close calls with deer auditioning for hood ornaments.

 

Halogens have a weaker and yellower output than HIDs, but you can't place a HID bulb in a traditional rear reflector because it cannot provide a point source for proper focus.......enter a projector housing with a convex lens in front of the source to focus the light output. But, problem is unlike a dual filament or two separate halogen bulb reflectors to accommodate different focused beams for high and low there is only one focused output for the convex projector lens. And absent four projector headlamps, with a two headlamp system lenses are focused on high beam, low beam is simulated by a mechanical shutter in the headlamp housing which draws an opaque curtain to block a portion of the beam leaving only the portion covering the low beam area. (You can hear the click(s) coming from under the hood when you open the shutter twhen switching to high beam). On low there is meniscus that leaves a sharp cutoff of the beam visible in the distance which is not only annoying, but reduces the amount of light projected from the bulb on low.

 

Solution is to place the more powerful, white output LEDs in a reflector housing to regain full output of the light source. The '19 Silvy, like the '18+ Traverse's stock LEDs use a separate prefocused rear reflector housings, the latter with rear reflector housing and focused "D" lenses setup. Unlike projectors, these systems do not use shutters to cutoff beams like the projectors, but instead use a separate reflector housing for each LED providing full prefocused output for each  beam. These setups use six LEDs in six separate housings, four dedicated for low beam and two four high beam, but the beauty of the system is that with independent prefocused housings all six LEDs (4 low + 2 high) remain on when on high beam giving a an unbelievable amount of light. So much brightness and coverage that I cannot understand how I'm never flashed on when on low beam, and Sunburn the deer on high.
