I got some real nice blue bulbs off ebay. My friend has them in his Civic without any modification to his lights to make them fit. The size is H4. I previously had 9004 size in my car. I need to know if H4 will also fit in my Integra...anyone know?? Thanks.

 

No. It's a dual filament bulb.

What's wrong with 9006?

 

Civics use H4s, that's why they fit on your friend's.

Integras use 9006 (low) and 9005 (high) bulbs.

 

Because I got them on ebay thinking I could ask for any size but he only has H4's.

So an H4 will work on other stock cars, like Civics, but not an Integra? It looks exactly like a 9004 bulb that I had before...

 

Alright. So what you're saying is to get some nice 9005 bulbs? I got some 20 dollar 9004 Philip's "hyper whites" at Walmart but they don't really look different. My friend has the H4's in his car. He got them for $45 and they are actually blue. It looks awesome. Anyways, so I should look at some 9005's than?

 

I have a 2nd gen, and on PIAA.com it says I need 9004's, like I was using. 9005's and 9006's are for 3rd gens. So, I just bid on another auction for the Nokya Blue bulbs in 9004 size for $14.99 Thanks anyway guys.

 

yes h4 is what you need. some people need to know what generation you drive and they might know and then others dont think about the 2nd gen's having only one main headlight. anyhow h4 is the buld model for your car.

 

9004's have a large plastic base, and the H4's have 3 flat metal parts coming out from the sides and no plastic. Thats the difference in how they mount. They also plug in differently to the little wire box.

 

my mistake i was thinking that the h4's and the 9004's were the same thing but i remember that they arent now sry people. only 9004 will fit into 2nd gen acura integra's.

 

Alright. Thanks everyone.
