The Honda 31510-ZE2-H91 is a genuine OEM Lamp Coil Assembly (12V/25W) designed for a range of Honda engines, generators, and lawn mowers. As a direct Honda OEM component, it is manufactured to the exact specification required for proper lamp circuit output — ensuring the correct 12-volt, 25-watt output your machine's lighting system depends on. This assembly is compatible with GX270 horizontal shaft engines, GXV140 vertical shaft engines, EX3300 and EX4500 generators, and HR195 and HR215 lawn mowers. Because Honda supersedes parts at serial breaks, confirm your machine's serial number against the fitment table before ordering.
Key Features
- Correct Output Rating — rated at 12V/25W to match the lamp circuit specification Honda engineered into these machines, so lighting output is consistent and the circuit is not overloaded
- Genuine Honda OEM Part — supplied directly from Honda's parts program under part number 31510-ZE2-H91, with no substitution or remanufacturing
- Broad Fitment Across Multiple Machine Classes — fits GX270 horizontal shaft engines, GXV140 vertical shaft engines, EX3300 and EX4500 generators, and HR195 and HR215 lawn mowers
- Check Your Serial Number — Honda updates part specifications at production serial breaks; verify your unit's serial number against the compatibility table to confirm this is the correct assembly for your machine
- Restores Lamp Circuit Function — a failed or open lamp coil eliminates lighting output entirely; replacing it with this assembly returns the lamp system to normal operation
The lamp coil assembly is a dedicated winding within the engine's charging or magneto system that generates the alternating current used to power the machine's work light or auxiliary lamp circuit. Unlike the main charging coil, which may serve the battery or ignition, this coil is wound specifically to deliver the voltage and wattage the lamp load requires. When the coil winding degrades or fails — through heat cycling, vibration fatigue, or a shorted turn — the lamp will dim, flicker, or go dark altogether. Installing a replacement lamp coil assembly restores that dedicated output and brings the lighting circuit back to its designed operating condition.
