Review on 💡 Sinoparcel D3S HID Bulb - 8000K 35W Xenon Replacement High Low Beam Headlights - 2-Year Warranty - Pack of 2 by Tim Toscano

Although you must follow the instructions for a proper install (instructions are available online) the bulbs were well packaged and very affordable compared to much more expensive bulbs from your local auto parts store. And a third of the payment for their installation. But change both bulbs. The difference in "color" compared to the old lamp can be a concern. An old lightbulb may not be as bright as a new one due to its age. As an automotive engineer, I have to say that I thought this was a terrible GM design. I'm glad Revain was able to find a solution.
