There was a small tab across from the one in the picture. I removed it with a
utility knife.


I made the three slots wider to accept the different spacing and size of the
tabs on the H9 bulb.


This is the tool I used to modify the slots a little at a time.


Here is the bulb installed.

 

Thanks for the clear pictures and write up!

So can you still fit H11 bulbs in there?

 

ill try this modification next time that i have time, thanks a lot for giving a clear description of what to do.

 

Not that it matters but...
Can you still use an H11 bulb or does it fall out now that you modified the housing?

 

Yes the H11 still works. It will still turn to lock in.

 

Next time I will remember to do the "before" pictures.

 

You can also just modify the light bulb itself and leave the housing stock. It took me less then two minutes to cut the tabs, plastic and metal, on both bulbs down to size. I cut the plastic rib out as shown above with a pair of wire cutters, then used the dremmel to grind a small amount off of the largest tab.
Stock H9 tab, largest one...

great write up... and thats a pretty big difference in light output

 

I looked all over and could not find anyone that stocked the H9 bulb.


Finally ordered some H9's from a parts store , stock bulbs, no light stealing blue tints, for $16 each. Hopefully they will get here in the next day or two!

For the guys that did this already, how would you describe the difference in light output? Not the actual percentage, but the observed difference between the different bulbs? Is it something that you think everyone should do, or is it something that you would say take it or leave it?

 

great info..

i get enough flashes from people who thinks my yellow fogs are too bright.. i might end up putting in some HID fogs :-)

Well, I picked up the bulbs last night and modified them to fit the housing and plug. Installed them this morning! I installed the driver side and did a compare! The new bulb looks a lot whiter and slightly brighter!!

The real test will be tonight when it gets dark! Hopefully the difference will be night and day, LOL!

My wife looked at me funny when I told her I was changing out the bulbs on the new car. "What was wrong with the old ones?" Women!

 

What good comes from converting these bulbs?

 

1350 lumens from the H11, 2100 lumens from the H9

about 50% more light output, that is what comes from converting. At least, that is what they are rated at. The H9 has 10 more watts of draw, but does not have the top of the bulb covered with a shield.

 

please dont forget to take pictures for us !!!

thanks

 

scroll up... you'll see the pictures of the light output differences

 

sorry to bring up old thread..

I just finished this mod. i did "widening the hole" way for future bulb fitment...

first impression at night?

more visible light on both sides of the road

more brighter light right infront of the car

Thanks...
