I waited a long time before making the switch on my 2019 Tahoe Z71 from the OEM halogen bulbs. LED technology has definitely improved over the last several years, so I'm glad I waited as things developed. About 2 months ago, I switched my low beams over to Lasfit LS Plus LED bulbs based on another members recommendation. I can tell you that the beam pattern is perfect and matches the factory halogen cutoff perfectly. The amount of light hitting the road is a night and day difference (no pun intended). I've always struggled with these stock halogen headlight bulbs at night, so it's really nice to see such a plug and play solution that actually worked perfectly.
As others have mentioned, clocking the LED bulbs correctly is crucial. The LED diodes need to be at 3 and 9 o'clock for light to correspond correctly inside the stock housing. It's also equally important to make sure that whichever LED bulb you use has the position of the LED diodes in the same relative space as the OEM halogen bulb filament. If the LED bulb chip placement is too long or too short, it compromises the pattern and output. It's for these reasons that I went with the Lasfit LS Plus LED bulbs. For about $100, it's a fantastic solution to the poor visibility from the OEM halogen bulbs. I can see the road MUCH better and I've yet to have any oncoming drivers high beam me.
