Chevrolet G-Van Engine Compartment Light Bulb Size

The Chevrolet G-Van engine compartment light uses 2 bulb sizes: 232 and 5008. The replacement chart covers vehicle production from 1992 to 1995.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Bulb Size by Year Range

Description	Bulb Size
ANSI standard (US & Canada). Festoon bulb with SV8.5 base. 12V, 3W.	232
ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. Lower wattage variant of 1156. 12V.	5008

The Chevrolet G-Van engine compartment light uses two distinct bulb types across the 1992-1995 model years: the 232 and the 5008.
The 232 is a festoon-style bulb, meaning it is cylindrical in shape and held in place by contact at each end rather than by a base socket. It operates on a SV8.5 base at 12V and 3W.
The 5008 uses a BA15s bayonet base, a single-pin twist-lock mount common in automotive applications. It operates at 12V and is a lower wattage variant of the 1156 bulb.
Both the 232 and 5008 conform to ANSI standards applicable in the United States and Canada.
The 1992 and 1995 G-Van share the 232 bulb for the engine compartment light, while the 1993-1994 models use the 5008 instead.
Because the 232 uses a festoon mounting and the 5008 uses a bayonet base, the two bulb types are not physically interchangeable despite serving the same function in the engine compartment.
The 5008 and the 1156 share a BA15s bayonet base, but they are not equivalent in wattage. Substituting a 1156 for a 5008 would introduce a higher wattage draw than the original specification.
