I was skeptical about the lights due to the reviews as well, but I haven't had any problem with them so far and I've had them for about a year now. The kit I bought came with inline capacitor and that helps with the flickering and lights coming on right away, but I also have a relay harness that illuminates all issues I could have.
Here's my 2015 Silverado LT1 4x4 5.3
So far it has a 2.5 level kit up front, 15% tint all the way around, OEM color match grille, HID headlights and fog lights, 3" cube leds mounted on brackets under hood hinge.
Coming soon
All terrian tires, black bow ties, blackbear tune, 30" light bar behind grille, color match headlight bezels.
