The Mobility Ventures MV-1 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2014 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type specified across all headlight positions in the Mobility Ventures MV-1, covering both high beam and low beam functions for the 2014-2017 model years.
The 9003 bulb is a dual-filament halogen type, meaning a single physical bulb contains two separate filaments: one dedicated to high beam output and one to low beam output.
Because the 9003 serves both the high beam and low beam positions in the MV-1, both headlight circuits draw from the same bulb socket and housing assembly.
The 9003 bulb is electrically and physically equivalent to the H4 bulb, a designation more common in European markets. These two part numbers refer to the same bulb and are interchangeable in fitment.
The 9003/H4 bulb operates at 12 volts and carries standard wattage ratings of 60 watts on the high beam filament and 55 watts on the low beam filament.
The dual-filament design of the 9003 means that failure of one filament does not necessarily disable the other, though the entire bulb unit requires replacement when either filament burns out.
The consistent use of the 9003 specification across all four model years indicates that the headlight housing assembly remained unchanged throughout the 2014-2017 production run of the MV-1.
