This H4 Rally bulb is a unique, non-standard type bulb. The low beam is the factory 55W filament, but the high beam is 100W (vs. factory 60W). This means a SIGNIFICANT increase in light output when in high beam. HOWEVER, this bulb also produces vastly more heat and can easily melt wires or light housings. Use with caution.
