Review on Enhance Visibility with GenXenon D5S 35W Xenon HID 6000K White Replacement Headlight Light Bulbs - 2 Pack by Jerry King

I had a problem with the bulbs but the customer service was good. The lamps are better than my original 2018 Sierra, a bit brighter which helps. But in my case I'm not sure why the bulbs weren't working properly but the dealer said and sometimes the bulbs don't fit gave me a few things to check and try and if it didn't work he said disconnect those Battery to reset the system. Did that and now it works perfectly. Not bad for the price but that customer service was helpful and lifelong can't go wrong.
