For the 2019 Cadillac Escalade, the supplied fitment data lists LED bulbs for both the low-beam and high-beam headlights. No separate replaceable halogen headlight bulb size is provided, so confirm the original lamp assembly and replacement method before ordering. The data does not list a fog-light fitment for this model year.
Most of the 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. The front turn signal is the main listed incandescent-style exception, using a 7440A bulb.
For the license-plate lights, the supplied options are 2825 and 98; verify the bulb currently installed before purchase. Interior lighting is listed as LED for the dome, map, trunk, and other interior lamps. No projector or non-projector-specific variation is included in the supplied fitment data.
