Kubota RTV500 4x4 high beam and low beam headlight bulbs both use 881 size bulbs. The replacement chart covers 2015 to 2018 vehicle production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 881 bulb is the sole bulb type specified across all headlight positions in the Kubota RTV500 4x4 headlight bulb specifications.
The 881 is a halogen bulb belonging to the T3.25 wedge-base family, operating at 12 volts and rated at 27 watts.
The 881 bulb uses a two-pin connector base, which is distinct from the single-contact bayonet or screw bases found in other automotive bulb families.
For the Kubota RTV500 4x4, the 881 bulb size applies to both the high beam and low beam headlight positions across the 2015-2018 model years.
The use of a single bulb type for both high and low beam functions indicates that the RTV500 4x4 headlight assembly does not employ a dual-filament arrangement; each beam position is served by a separate, dedicated 881 bulb.
The 881 bulb is closely related to several other bulbs in the same series, including the 880, 885, 886, and 894. These variants differ in wattage and light output, and substituting them without confirming socket and voltage compatibility may result in improper fitment or electrical issues.
Because the same 881 specification is shared across both beam positions, a single replacement bulb type covers all headlight sockets on the vehicle, which simplifies parts procurement.
