[LRP_LS400]

does anyone know what type of bulb is used for the jdm one piece headlight? i just installed the jdm headlight and i'm using the stock bulb 9004 and the light output is horrible; i cant see more then 7-8feet infront of the car. any info is welcomed. thanks

to answer my own question. the jdm bulb size is H4 so in order to have them fit an adaptor is need to conver the 9004 harness to H4 bulb.

Hi LRP, have you looked at the lexls how to on lighting, I'm sure it's there I saw how to use a H4 bulb with nothing more than 6" of wire and a ring terminal.
