Look up 9011 and 9012 bulbs on amazon. They are HIR or HIR2 and have more lumens and can be modified (really easy) to work for 9005 and 9006. There life is longer than a stock bulb.
9005 = 1000 lumens (55 watts)
9011 = 1759 lumens (55 watts)
9006 = 1800 lumens (65 watts)
9012 = 2800 lumens (65 watts)
Everything was typed from memory.
I run the 55 watt low beams.
