Ram 3500 Glove Box Bulb Size

Additional Notes

• The Ram 3500 uses the 194 bulb for the glove box across the 2011-2024 model years, with no variation in bulb type across this range.
• The 194 is a miniature wedge-style bulb built to the T10 form factor, which refers to a tubular glass envelope roughly 10 eighths of an inch wide, seated in a wedge base that requires no separate socket pins.
• The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of interior illumination applications.
• The 194 designation follows the ANSI standardization system recognized in both the United States and Canada, meaning bulbs carrying this designation from different manufacturers share the same electrical and physical specifications.
• The T10 wedge base format allows direct plug-in replacement without tools, as the base itself acts as the electrical contact when pressed into the socket.
• Because the 194 is an ANSI-standardized type, LED replacements built to the same T10 wedge base are generally available, though compatibility with the vehicle's specific socket depth and housing clearance is a relevant fitment consideration.
