The Jeep Renegade dome light uses bulb size 12961 and bulb size DE3423 according to the provided specifications for the interior lighting components. The available data covers the range from 2015 through 2023 for the specified vehicle and lighting application.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep Renegade dome light uses two distinct bulb types across its model years: the 12961 for 2021-2023 and the DE3423 for 2015-2018.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge base on the 12961 relies on friction-fit metal contacts along the sides of the bulb's plastic wedge, rather than pins or end caps.
The DE3423 is an ANSI-standardized festoon bulb recognized across the US and Canadian markets, operating at 12V with a 41mm length and end-cap contacts.
Festoon bulbs make electrical contact through metal caps at each end of the cylindrical body, which seat against spring-loaded clips inside the fixture.
The 12961 and DE3423 use fundamentally different base types, making them physically non-interchangeable despite both serving dome light functions on the Renegade.
The front dome light position on the 2021-2023 Renegade specifically takes the 12961 bulb, consistent with the general dome light specification for those same years.
