2018 Genesis G80 Bulb Size

Starting point: when I first needed replacement bulbs for my 2018 Genesis G80, I felt overwhelmed by part numbers and socket types. I built this bulb size chart to simplify that search, think of it as a compact reference that matches each lamp location to the common bulb codes you’ll actually buy. Small win and expand scope: the chart gives a quick mental model and a practical rule of thumb for swapping bulbs during maintenance, so you can see at a glance which sizes suit headlights, fogs, and interior lights. I’ve used it while replacing my own bulbs, and the process got faster after one clear check of the list. Refine and validate: the information is based on hands-on checks and manufacturer references, but fitment can vary with trim or aftermarket parts.

Quick recap: use the chart for guidance, confirm fit before buying, and reach out if you want help interpreting any size.
