The Toyota Matrix dome light utilizes a DE3175 bulb size for illumination within the interior cabin area of the vehicle. Available specifications for the component cover a range from 2003 to 2013.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Matrix uses the DE3175 bulb across all dome light positions for the 2003-2013 model years, making it the sole bulb type specified for this vehicle's interior overhead lighting.
The DE3175 is a festoon-style bulb, meaning it is cylindrical in shape with metal end-cap contacts at each end rather than a base or pin configuration. It seats by pressing lengthwise into spring-loaded clips within the fixture.
The DE3175 has a specified length of 31mm, which is a standard festoon size. Substituting a festoon bulb of a different length, such as 28mm or 36mm, would result in poor contact or failure to seat properly in the fixture.
The bulb operates at 12 volts, consistent with standard automotive electrical systems. Using a bulb rated for a different voltage risks premature failure or insufficient output.
The DE3175 designation follows the ANSI standard recognized in both the United States and Canada, meaning the specification applies uniformly across North American market vehicles.
For 2003-2008 Toyota Matrix vehicles, the front dome light and rear dome light are each listed as separate positions, both requiring the DE3175. This indicates the two fixtures are independently replaceable but share the same bulb type.
Because the DE3175 is used in both the general dome light position (covering 2003-2013) and the individually listed front and rear positions (covering 2003-2008), a single bulb type services all overhead interior lighting across the full production run of the Matrix.
