I just got a Hella headlight conversion kit and put the H4 bulbs in it that came with the kit. I was curious if anyone sells a better H4 bulb that would be brighter. Let me know thanks!

 

It all comes down to personal preference. Once you upgrade from stock halogen you lose 50% of the bulbs life. Not so much if you don't run the headlights all the time like with DRL's but they still run half as long as standard bulbs. You will hear good things about Philips X-treme Vision or GE Nighthawks. I've ran both and I like the brightness of both but I prefer the Philips over the Nighthawks. Then there are Silverstars which I've also tried but I didn't find them as bright or last as long as stated.

 

Is there an H4 option that comes in a more 6000k color range?
