The SM 9105 is a heavy-duty "Platinum Series" halogen bulb designed for 24V commercial electrical systems. Featuring the standard H4 (P-43T) three-prong base, this high-wattage variant delivers 100W on high beam and 90W on low beam. It is the ultimate lighting solution for long-haul trucks and buses operating on dark highways, providing a massive increase in light volume compared to standard 75/70W commercial bulbs.
