2021 Cadillac Escalade bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not list separate replaceable headlight bulb sizes or indicate a projector versus non-projector headlight variation, so verify the original lamp assembly before ordering.
Most exterior lighting is also LED, including the daytime running lights, parking lights, front and rear side markers, tail lights, rear turn signals, brake lights, center stop light, and reverse lights. No fog-light bulb fitment is listed.
- Front turn signal: 7440A.
- License plate: 2825 or 98, depending on the lamp configuration.
- Interior lighting: LED is listed for the dome, map, trunk, and other interior lights.
Because many functions are identified as LED rather than conventional replaceable bulbs, replacement may involve the complete lamp or LED module instead of a standard bulb. Confirm the existing component and socket before purchasing.
