Toyota Pickup Dome Light Bulb Size

Additional Notes

• The Toyota Pickup uses the DE3175 bulb size for the dome light across all listed model years, spanning 1986-1995.
• 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.
• Festoon bulbs are held in place by spring-loaded clips that press against the end caps, a mounting method common in interior dome light housings.
• The DE3175 has a nominal length of 31mm, which is a critical fitment factor, as festoon bulbs must physically span the distance between the two contact clips in the housing.
• The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
• The DE3175 designation follows ANSI standards recognized in both the United States and Canada, indicating the bulb conforms to a defined set of dimensional and performance specifications within those markets.
• Because the DE3175 is an ANSI-standardized part, bulbs carrying this designation from different manufacturers are generally interchangeable, provided the 31mm length and end-cap contact design are maintained.
