Those with gt86 jdm headlights
 

I believe these are d4s bulbs. Correct me if I'm wrong please. I'm lookin to get some 6000k bulbs for my new headlights.

I am pretty sure they are D4S like you said. Somewhere on this forum it is confirmed exactly what they are, but I couldn't find the post.

The only google result I found was

It does seem to confirm your question though. I have been meaning to get some new bulbs too, are you looking at a specific type?

The D3 and D4 bulbs are the same, we have replacements listed on our site for $39.99

here is a link:

We have more information on the site regarding D3 and D4 bulbs, check the knowledge base.

Otherwise, I can answer any of your questions
