Hey- I recently Bought H7 6000k HID replacement bulbs for my 2009 RX-8 Sport.
I feel that they aren't bright enough on the road, Is there any way I can make them brighter, Or would I need to buy new bulbs?
Thanks!

 

6000k is not as bright as stock... no way to fix it... get oem philips 5200k and be happy lol or live with the dimmer 6000ks.

 

i have actually seen 6000k that "seemed" brighter than my oem HIDs. This was side by side.

 

You have to upgrade the ballast to a 55 watts-- oem only draws 35 watts. However, replacing the oem ballast is not easy.
