36V 25W Bulb – 35-559

This replacement bulb is rated 36 volts at 25 watts, built in the compact S8 bulb profile with a bayonet base, the connection style used across the small warning and work lights mounted on electric lift trucks and pallet jacks. S8 describes the bulb's glass envelope shape and size, a small tubular profile common to indicator and accessory lighting rather than headlamp or floodlight applications, and the bayonet base locks into its socket with a twist-and-lock action rather than threading in. Physical dimensions run 0.99 by 1.91 by 0.4 inches, small enough to confirm this is sized for a compact instrument or warning light housing rather than a larger work light.

Several lift truck and pallet jack brands share this same 36V, S8, bayonet-base lamp footprint across their small accessory lighting, which is why matching the base style and voltage against the bulb currently in the fixture is the reliable way to confirm fit rather than matching by truck brand alone. As a wear item, the bulb's filament degrades with use and heat cycling, typically showing as dimming output or flickering under vibration before it fails outright, the point at which the light stops giving its warning or work-area illumination. Replacing it at the first sign of dimming keeps the fixture doing its job rather than running dark on equipment where a warning or work light matters for visibility.
