I just received my new ACA projector lights and plan on getting an HID kit. My question is, is there a difference from the HID h9 bulb vs the HID h11 bulb??? (55watt slim balast)

Thanks

Mr.Bill

Not sure what the difference is, But both should fit. I installed H9 in mine.

Did you have to mess with the bulb socket at all? Do you have high/low beam on the bulb or is that from the separate lamp? Thanks

HID H9 and H11 are the same bulb.

Thanks jon , I had read that on stock bulbs the light out put was different and that the portion where it clips in the lamp was also slightly different...just wasn't sure if it applied to hid's also. Thanks

Mr.Bill

My H9 is just lo-beam, The other socket is for the Hi-beams.

You'd do far better with this Bi-xenon upgrade:

Are the stock aca's not sufficient with hid's that they need to be modified or is just a further improvement on a already decent system? Thanks

They are a far cry from the candles of the factory lights, but if you're going to upgrade to HID anyway, you might as well upgrade to the best. The bi-xenon system I build offers many advantages including:

- Bi-xenon projector (allows the projector to function both as low and high beam with no additional light source needed)
- Correctly aligned low and high beam (from the factory, your low beam is NOT properly aligned with the highs.
- "tuned" projector optics for a more uniform light distribution on the road
- Significantly wider pattern to see objects on the side of the road as well as around turns
- Foreground limiter to reduce glare
- Direct plug-and-play HID kit included

Got mine last year. Best money I ever spent. I was amazed at the difference it made.
