2018 Cadillac Escalade bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify a replaceable halogen headlight bulb or list a projector/non-projector variation, so verify the original headlamp assembly before ordering replacement parts.
- Headlights: LED low beam and LED high beam.
- Front turn signals: 7440A.
- Exterior lighting: LED reverse, brake, center stop, daytime running, parking, front and rear side-marker, tail, and rear turn-signal lights.
- License plate: 2825 or 98, depending on the lamp configuration.
- Interior lighting: LED dome, map, trunk, and other interior lights.
No fog-light bulb fitment is provided for this model year. Because many applications are integrated LED assemblies, check the vehicle’s existing socket or lamp housing when replacing an individual bulb.
