yeah the h4's are definately brighter and i can get higher wattage bulbs aswell, although it does recommend using a certain material casing from the extra heat of the bulbs, my low beems are brighter compared but my high beems are definately brighter, only prob is i don't have parkers, but the bumper does n wen on earth do u use parkers newaz. your welcome here lol its always good to have international members, you find out some intersting new things bout rolla's especially ke**

 

Did you put in some different coloured light globes than the regular ones?

Like, I had a browse on the net for H4's, and there are different colours to choose from: yellow, white, blue, and ultraviolet:

 

H4 bulbs

 

I've got sealed beams at the moment, so I can't swap to brighter globes. I think I've got 50 watts for low beam and 75 watts for hight beem, or somewhere around there.

I might get the head light surround, then put brighter globes into that.

ive got 60w halogen globes from supercheap , originally i had 55w sealed beams n I'm looking at brighter bulbs maybe something slightly whiter

I had a choice of yellow but alot brighter or the blue/white look. obviously i took the yellow but brighter ones as i did all my driving at night at that time.the are really good.cost 25 for both bulbs. :P

sounds bout right , the warmer the colour ie yellowish produces more lumens so effectively brighter but the higher the burning temp the easier it is to see to a certain degree, so yellowish or just normal bulbs make it easier to see but the others white/blue are brighter,and of course the higher the wattage the brighter

Has your corolla got black carpet??
