I have PIAA 525 Auxiliary Lights. Those are dual beam lights, so they use H4 type bulb. After having them for a few months I've decided to upgrade them to something more powerful. Mine has PIAA Xtreme White 60/55W =100/110W 4000K. Does anyone know any higher wattage bulbs? What about JAOS ones, are they really using 120/100W bulbs or they have the same technology as PIAA, 60/55W which is equal to 120/100W?
