If you want brighter bulbs you arent gonna really find any, there are a few that are like 130w but are far too bright and glare like a b!tch for road use, youd also prob burn the standard wiring as its not up to much. Your best option for noticably improved lighting would be a full hid retro fit kit as the light would be 3x brighter but still acceptable for every other road use at the same time, so long as you got the correct type of bulb for your headlights. There are different bulbs for different headlight styles, if you have standard lights youd have reflector lenses, if you have aftermark
