Buick Regal TourX Bulb Size By Years
I started this bulb size chart because I once struggled finding the right replacement for my 2019 Buick Regal TourX, and that frustration shaped a practical list. Think of it as a mental model: match bulb type and fit to the factory sockets, then confirm brightness and color temperature as preferences. That quick win gets headlights and interior lights working correctly without guesswork.
As I expanded the chart, I added common alternates and notes about CAN-bus issues and load resistors, so you can make small upgrades confidently. A simple rule of thumb I used was to verify both the bulb code and the socket shape before ordering, which saved me returns and time.
Quick recap: use the list as a starting point, cross-check fitment, and choose brightness to taste. Some links may be affiliate links, and I may earn a small commission at no extra cost to you; the recommendations reflect my experience and aim to help you find the right bulbs.
