just bought the jdm 1pc's for my da... i was wondering if i can use the bulbs that came with the usdm lights or do i have to buy h4h?

 

if you want to use the usdm headlight bulbs you will have to trim it to fit.

 

just buy H4H bulbs...

people have shoved a 9004 bulb in place of H4H before that i wont lie... but its not the correct way since filaments don't align correctly.

 

okay i bought a pair of h4h bulbs & the jumper harness from password... anything else i need? do i need these? http://passwordjdm.com/PasswordJDM-H...s-P971C77.aspx
new to this........ here's a pic of the lights

 

your pictures dont work..

anyways... this would be easier to use since its plug and play.

just plug that into the stock harness from the car and and the other end plugs into your bulb.

BUT, if your headlights came with the H4/H4H connector... you could just cut/splice that into your existing headlight bulb wiring.

but the easiest would just to use that jumper harness password sells.

 

yea I already have the jumper harness on its way but what's this other harness for? and do I need them? http://passwordjdm.com/PasswordJDM-H...s-P971C77.aspx

that "other harness" is basically what you already have... its for people who bought headlights that didnt come with the H4/H4H bulb connector and want to wire it into their existing wire harness.

and dont you already have bulbs... looks so from the pictures.

 

o i see. yea i do have bulbs but i'm not sure if they're working or not. thanks for the help!
