Honda Wagovan front turn signal bulbs utilize 1156 or 1157 size specifications, while rear turn signal bulbs require 1156 size. The replacement chart covers 1984 through 1987 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 bulb is a single-filament unit operating at 12V with a 21W output, fitted with a BA15s bayonet base. It conforms to ANSI standards applicable in both the US and Canada.
The 1157 bulb is a dual-filament unit sharing the same 12V operating voltage but carrying two wattage ratings of 21W and 5W. Its BAY15d bayonet base physically differs from the BA15s base of the 1156, making the two bulbs non-interchangeable despite their similar appearance.
The dual-filament design of the 1157 serves two separate circuit functions within a single housing, which is why its base has offset pins to prevent incorrect installation.
The Honda Wagovan front turn signal uses the 1156 bulb for the 1986-1987 model years and the 1157 bulb for the 1984 model year, indicating a change in front turn signal circuit design across these years.
The rear turn signal on the Honda Wagovan uses the 1156 bulb across all three listed model years, 1984, 1986, and 1987.
The 1984 Wagovan front turn signal specifies the 1157 dual-filament bulb, while the rear turn signal for the same year specifies the single-filament 1156. These two positions therefore require different bulb types on the 1984 model.
For 1986-1987 Wagovan models, both the front and rear turn signal positions share the same 1156 bulb specification, allowing a single bulb type to serve both locations in those years.
