Is there any difference between a car H7 12v 55w bulb and one specifically for motorbikes. I ask as I was flicking through the Philips shop for new bulbs for my bike and saw Racing ones which give 150% more light, 130% light but they only show up in the car search. If you search under Moto it just offers the X-treme Vision Moto which gives 100% more light. What would be the difference. Any other ideas on a bright light from other makers.
