Review: NO para Silverado 2016 - Dice que es compatible para Silverado 2016, pero está equivocado.
Review: Bright Bulbs - Nice Flashing Effect - I can't rate this LED bulb on longevity because I haven't had it very long. Maybe a year from now I can, but I honestly expect to last several years, not just one. As for ease of installation, well that is more a reflection on the vehicle manufacturer than it is the bulb manufacturer. Remove 4 phillips head screws, remove the third brake light lense cover, and there's you bulb. Pop out the old, pop in the new, and put it all back together again. The bulb is much brighter than a conventional bulb, and requires less power to do so. I also like the flashing effect. It flashes a few times then goes to solid and stays solid until you release the brakes. Once you apply the brakes again, the process repeats. The whole reason third brake lights came into existence was to get drivers attention, and alert them you were slowing down or stopping. Now that they have been out 20-30 years, drivers are getting complacent again. This light flashing brightly a few times before going solid red helps get their attention again. I don't want anybody hitting me from the rear, or any direction for that matter. I think these bulbs are a great safety addition to my truck. If it helps prevent one accident, then it was worth the price...and I might add that these two packs of bulbs were pretty cheap to begin with. I hear they are illegal in some states, so you might want to check your local laws before you buy if you want. Me personally I don't care if they are legal or illegal... I am using them anyway. if some cop decides to write me a ticket for having them installed...well I'll take it, but they will remain. I like these bulbs and they serve a good purpose.

### ⭐⭐⭐⭐⭐ Good on install. No longevity. GARBAGE. See 2nd-3rd EDITs.
*by S***A on 1 August 2022*

I've bought various brands of LED lights for various vehicles. Nearly all fit the vehicles as ordered and functioned well on install. And everyone seems to write e review only on install. Sure. They all work and look great. The trick is to find a brand that has longevity. The plethora of XYZ Ltd. Chinese companies stamping these bulbs out by the millions is completely bewildering. In this case, competition seems to breed poor quality for a cheap price. So many of them are so crappy, when they quite after a few months of their "100,000 hours lifespan", you curse a few times, throw them out and order a different unknown brand and take another chance. These guys offer a 5 year warranty that I activated on their website a few minutes ago. Beats me how to make a claim if I have to. I would really rather pay more if I could trust that I won't be swearing at them in 3 months when they are flickering. On initial simple install on the center brake light of my 2002 Suzuki Gran Vitara XL7, the lights flash 3 times and come on nice and bright...just as the company promises. Now we wait... EDIT: Nearly 2 years later and they are working flawlessly!! EDIT: 2 years later. 1 of the 2 has quit. One side of the bulb is a dull red glow. I put the OEM bulb back in and ready to swap out the other when it goes. The SUV is driven little so these LED have seen little use. Typical Chinese quality LED. 30,000 hours???? Sure. Maybe 30,000 minutes. GARBAGE. EDIT: 2 years 2 months. The second one has died. I've reinstalled what are likely the original incandescent bulbs from 2002 model year Suzuki Grand Vitara. $12 each for these LED flashers. 2 years at 50% highway use on 12,800 kms total use. Save your money. Buy something else.
