ok i just bought some black halo headlights and they are not very bright i need to know how to replace the bulbs i guess and/or which bulbs or what i need to do to get them brighter.

 

It's going to be a 9003 I believe. For sure it's a single capsule has both bright/dim filaments. Get the Sylvania Silverstar Ultras. They are twice as bright as the regular Silverstar lamps. A little pricey, but they are worth it!!!

 

they run a 9005. i have those headlights and they use a two bulb system so you should also buy the wiring harness that allows you to use both lights when you hit ur brights. i have the white piaa light bulbs. they cost alot but they are the best. that is my opinion though.

 

HID's.... google: HID kits warehouse

 

Are u using the oem harness? Also alot of the ebay units are misswired. Are they the dual halo like mine? Mine were misswired out of the box which produced a very dim low beam and lazy high beam. On low beam the high beam indicator on the dash would be lit which is a clue.
