The Lexus LX470 dome light requires a DE3175 bulb size for proper installation and function within the interior lighting system. Data for the specified component covers the range from 1998 to 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The DE3175 is the sole bulb size specified across all dome light positions in the Lexus LX470.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 has a 31mm length, which is the critical physical specification governing fitment in the festoon socket housing.
The DE3175 conforms to ANSI standards applicable in the United States and Canada.
The Lexus LX470 (1998-2007) uses the DE3175 for its general dome light position across the full model range covered by these specifications.
The rear dome light position uses the DE3175 across the 1998-2007 model years.
The front dome light position carries a separate sub-part designation and is specified with the DE3175 for the 1998-2000 model years.
Because festoon bulbs are sized by length, installing a festoon bulb of a different length in a DE3175 socket would result in improper contact or fitment failure.
The consistency of the DE3175 across both the front and rear dome light positions means the same bulb type serves all interior dome lighting in the LX470.
