i install some new hid light bulbs but they werent as bright...someone told me that i can change my housing on the headlight...does anyone know how to do it...thanks

 

If you're talking about the common blue coated "HID look" bulbs, the output is not going to be terribly good, and the actual color of the light makes them even less useful. Changing the housings is not going to improve their performance unless your current reflectors or lenses are in poor condition.

 

you should just buy the HID kit
