Cadillac SRX 2004 Bulb Size
Bulb size chart
This 2004 Cadillac SRX bulb guide helps you verify the correct bulb size by lighting position, so you can match each exterior and interior lamp without guessing. Because the SRX could be equipped with different lighting setups, it is important to confirm the exact bulb location before ordering replacements.
Use this page as a quick reference for headlights, brake lights, turn signals, parking lights, reverse lights, and cabin bulbs on the 2004 Cadillac SRX. The bulb chart is organized by position to make it easier to find the right fit for your vehicle and avoid buying the wrong type.
Fitment on the 2004 Cadillac SRX can vary by trim, market, and lighting package, so the same model year may use different bulbs in different positions. Some vehicles have halogen low beams while others use HID low beams, and aftermarket LED conversions may change what fits or what works correctly with the housing and electrical system. Before you buy, check the bulb currently installed in the vehicle, compare it to the chart, and verify whether your SRX has factory HID or halogen headlights, since that affects the low beam bulb choice. It is also smart to inspect the socket, connector, and lens area for signs of wear or previous modifications, especially if the vehicle has had lighting upgrades or repairs.
