For the 2020 GMC Canyon, the low-beam headlights use H11 bulbs, while the high-beam headlights use 9005 bulbs. The fog lights use 5202 LED bulbs. This fitment data does not specify separate variations by headlight type or configuration, so confirm the original bulb and housing before ordering.
Several exterior lighting positions use the same 7443 bulb: front turn signals, parking lights, front and rear side markers, brake lights, tail lights, and rear turn signals. The reverse lights, center stop light, and trunk light use 921 bulbs. License plate, dome, and map lights use 2825 bulbs.
When replacing the headlight or fog-light bulbs, compare the bulb base and connector with the vehicle’s existing part. In particular, the fog-light listing specifies an LED bulb, so use a compatible 5202 LED replacement for that position.
