Cadillac 13503417 Low Beam Bulb

To access the exterior light bulbs, for front turn signal and parking lights on 2015 and earlier models, remove the windshield washer reservoir filler neck if necessary. For 2016 or later models, remove the front fender liner for access. Twist the bulb holder counterclockwise to remove it, then replace the bulb and reinstall the holder. For front side marker lights on 2016 and later models, remove the headlight housing, turn the bulb holder counterclockwise, replace the bulb, and reinstall. For fog lights, remove the fasteners from the inner fender splash shield, pull it back for access, disconnect the electrical connector, twist the bulb counterclockwise to remove it, and reinstall in reverse order. The center high-mounted brake light, which is an LED fixture, requires removing the trim panel from the trunk lid for 2015 and earlier models, or lowering the rear section of the headliner for 2016 and later models to access the fasteners and electrical connections. For brake, tail, and turn signal lights, open the trunk, remove the rear compartment side trim, turn the socket counterclockwise, replace the bulb, and reinstall. For license plate light bulbs, pry down or out the lens depending on the model year, remove the bulb, and install a new one. For interior light bulbs, gently pry the overhead console from the housing to replace reading lights, pry the cover off the rear dome light to replace the bulb, and open the glove box to remove the glove box light bulb. Instrument cluster illumination is integral to the cluster and requires replacement of the entire unit if a bulb goes out.
