Peterbilt 200 Back Up Light Bulb Size

Additional Notes

• The backup light bulb specifications for the Peterbilt 200 cover model years 1974-2000, with two distinct bulb sizes appearing across that span: the 1156 and the 199.
• The 1156 is an ANSI-standard single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, and it serves as the backup light bulb for the Peterbilt 200 across model years 1993-2000.
• The 199 is also an ANSI-standard single-filament bulb rated at 12V and 21W with a BA15s bayonet base, and it is classified as a variant of the 1156. It applies exclusively to City Delivery configurations of the Peterbilt 200 for model years 1974-1978.
• Because the 199 is a variant of the 1156 and shares the same voltage, wattage, and base type, the two bulbs are closely related electrically and physically, though fitment should be confirmed against the specific vehicle configuration before substitution.
• The 1997 Peterbilt 200 carries two separate entries for the 1156 bulb: one for the standard configuration and one specifically noted for vehicles equipped with four rectangular headlamps, indicating that headlamp configuration is a relevant fitment variable for that year.
• Similarly, the 1996 model year lists the 1156 under both a standard entry and a four rectangular headlamp variant, mirroring the dual-entry pattern seen in 1997.
• The 1995 and 1994 model years each carry a standard 1156 entry alongside a separate entry designated for vehicles with four round headlamps, distinguishing that headlamp style as a fitment qualifier in those years.
• The 1993 model year includes a standard 1156 entry as well as a separate entry for vehicles equipped with halogen capsule headlamps, representing a third type of headlamp-based fitment distinction within the specifications.
• The BA15s bayonet base is a single-contact base, which is consistent with the single-filament design of both the 1156 and 199 bulbs listed throughout these specifications.
• No headlamp configuration qualifiers are noted for model years 1994-2000 outside of the specific years already mentioned, nor for the 1974-1978 City Delivery entries, where the only listed qualifier is the body configuration itself.
