Chevrolet Camaro Engine Compartment Light Bulb Size

Additional Notes

• The engine compartment light bulb for the Chevrolet Camaro is specified across model years 1967-1994, with three distinct bulb sizes appearing throughout that span: 1156, 93, and 1003.
• The 1156 is the most frequently specified bulb across the Camaro's engine compartment light fitment data, covering the majority of model years in the range.
• All three bulb types in these specifications share the BA15s single-contact bayonet base, meaning the physical base style is consistent across all listed sizes. However, the bulbs are not interchangeable due to differences in wattage and contact configuration specifics.
• The 1156 and 1003 both operate at 12V and 21W, making them identical in voltage and wattage, though they carry different ANSI designations and are not confirmed as direct substitutes within these specifications.
• The 93 bulb is a lower-wattage variant at 12V and 13W, drawing significantly less power than the 1156 or 1003, which affects the brightness output in the engine compartment.
• The 93 bulb is specified for the 1982, 1983, and 1985 model years, while surrounding years call for the 1156, indicating the fitment is not uniform across consecutive model years.
• The 1003 bulb is specified for the 1972, 1973, and 1979 model years, representing isolated fitment years within a broader span otherwise dominated by the 1156.
• All three bulb sizes conform to ANSI standards applicable in both the United States and Canada, classifying them as standardized automotive bulbs within the North American market.
