hi ! im about to buy jdm headlight for my 91' ls400... ive been told that the jdm headlight use H4(9004) and my stock headlight are currently using 9004. im buying Mtec hids tomorrow so i was wondering which one do i have to buy ? Mtec h3 or h4 ? will i have to buy a seperate harness?

please let me know

thanks in advance

 

JDM Toyota Celsior headlights use H4 which is 9003, not 9004. You'll need to get Mtec HIDs in the H4 (aka 9003) application. You could use a seperate harness to convert your 9004 to H4, but it would be easier to do some splicing or have a shop hardwire the kit for you.

 

alright thanks, h4 mtec hid ordered

 

If you need help with doing the wiring shoot me a pm. I have a '91 with JDM lights too and I had splice the wires also.

 

thanks ill let you know
