These are the business IMHO
Philips GT150 bulbs
They remain 55/60w but are 50% brighter than standard with a very clear white light. Apparently they emit no UV rays so wont bugger plastic lenses, dont get stupidly hot and are robust compared to higher wattage bulbs.

Cool as hell really

Helps you to see what your going to run over, or hop into you better as well
