Additional Notes

The Honda Ridgeline glove box uses four distinct bulb types across its model years: the 74, DE3021, 6428, and 13050.
The 6428 is the most frequently specified bulb across the Ridgeline's model history, appearing in the 2007-2009, 2011, and 2013 model years.
The 6428 is a festoon-style bulb with an SV8.5 base, a 36mm length, and operates at 12V with a 5W output. It is an ANSI-standard part recognized in both the US and Canada.
The DE3021 is also a festoon bulb but measures 31mm in length and uses end-cap contacts rather than the SV8.5 base found on the 6428. These two festoon types are not interchangeable despite sharing a similar form factor.
The 2017-2020 Honda Ridgeline uses the 74 bulb, a T5 miniature wedge type rated at 12V and 1.4W. Its wedge base design differs fundamentally from the festoon and halogen types used in earlier model years.
The 13050 is designated as an OEM/Wagner part number rather than an ANSI standard, which means it is sourced through manufacturer or aftermarket supplier catalogs rather than a universal industry classification. It is specified solely for the 2010 model year.
The 2006 and 2012 model years share the DE3021 specification, while the 2014 model year also uses the DE3021, making it the only bulb type to appear across three non-consecutive model years alongside the 6428.
All four bulb types in these specifications operate at 12V, consistent with standard automotive electrical systems.
The shift from festoon-type bulbs in earlier model years to the T5 wedge-base 74 bulb in the 2017-2020 range reflects a change in socket design, meaning earlier festoon sockets are physically incompatible with the wedge-base 74.
