The Dodge Rampage front and rear turn signal bulbs both utilize a 1157 size bulb for proper operation. The replacement chart covers vehicle production spanning 1982 to 1984.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 is the sole bulb type listed across all turn signal positions for the Dodge Rampage, covering both front and rear applications for the 1982-1984 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve both a higher-wattage function and a lower-wattage function from one unit.
The 1157 operates on a 12-volt electrical system and carries a wattage rating of 21W on the primary filament and 5W on the secondary filament, corresponding to its turn signal and parking light roles respectively.
The 1157 uses a BAY15d bayonet base, which is an offset twin-pin base. The offset pin placement is a deliberate design feature that prevents incorrect insertion, as the two pins are positioned at different heights around the base.
The 1157 conforms to ANSI standards and is recognized in both the United States and Canada, placing it within a widely distributed specification used across North American automotive applications.
Because the Dodge Rampage uses the same 1157 bulb for both the front and rear turn signals across all three listed model years, the front and rear positions are directly interchangeable with one another in terms of bulb fitment.
The BAY15d base of the 1157 is not compatible with single-pin bayonet bases or other multi-pin configurations, so substitution with visually similar bulbs carrying different base types would result in a fitment mismatch.
