The Jeep Dispatcher front turn signal requires a 199 or 1034 bulb size, while the rear turn signal uses a 1156 or 1034 bulb size. The replacement chart covers vehicle production spanning 1961 to 1969 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1034 bulb is the most widely used type across the Jeep Dispatcher's turn signal specifications, appearing in both the front and rear positions for model years 1961-1968.
The 1034 is a dual-filament bulb rated at 12V with a 21/5W output, using a BAY15d bayonet base, and is classified as an ANSI standard bulb for the US and Canada.
A dual-filament design means the 1034 bulb serves two lighting functions from a single unit, with the higher wattage filament typically handling turn signal or brake duties and the lower wattage filament handling a secondary function such as running lights.
The 1969 Jeep Dispatcher front turn signal uses a 199 bulb rather than the 1034 found in earlier model years, marking a change in front turn signal fitment for that year.
The 199 is a single-filament bulb rated at 12V and 21W, using a BA15s bayonet base, and is noted as a variant of the 1156 within the ANSI standard.
The 1969 Jeep Dispatcher rear turn signal uses a 1156 bulb, which is also a single-filament 12V, 21W unit with a BA15s bayonet base, consistent with the ANSI standard for the US and Canada.
The 199 and 1156 share the same BA15s bayonet base and identical voltage and wattage ratings, as the 199 is classified as a variant of the 1156, though they are distinct ANSI part numbers.
The BAY15d base of the 1034 is not interchangeable with the BA15s base of the 199 or 1156, as the BAY15d features offset pins to accommodate its dual-filament design while the BA15s uses a single-contact configuration.
For the 1969 model year, the front and rear turn signal bulbs both use single-filament types, whereas all prior model years in the specifications use a dual-filament 1034 for both positions.
