Also Hella and Philips make H4 bulbs in +30 and +50 output, but same wattage as stock. http://www.fosmo.com/
has a description of these bulbs. They all use a little xenon, not for color - for cooling. The improved light output is obtained by repositioning the filament. I have never bought from Fosmo, and some members have reported mixed results, but the site shows what is available.
Also, before you buy the color xenon look bulbs, you might want to read the test at this site:
Good luck on your choice.
