    Morimoto XB35 HID install help! Bulb won't fit in housing

    I've finally gotten around to changing out my HID system into Morimoto XB35 HID kit from K5optima store and I am having 2 fitment issues....

    1st problem i'm having is that I got into an accident couple of years ago and I've had my driver side headlight replaced. The shop that my insurance used didn't use Kia headlight but instead used OEM headlight.
    The issue is that the OEM model has a slightly different 3 prong tab spacing and I can insert the bulb into the 3 prong space but can't turn it to lock it in....
    Anybody have any clue on how this might be alleviated?

    2nd problem i'm having is that the bulb + the connection of the bulb to the ballast is too long and I can't close/seal the headlight cover....
    I've searched all through out this forum but haven't seen a single person with this issue.... any idea what the problem is? I'm having this problem on both OEM and Kia headlight.

    3rd problem is that the ballast are buzzing on both sides, even with use of relay and anti-flicker capacitor.... any clue what i should do?

    Thanks guys!

    Ok, I’m confused already. OEM and a Kia factory headlamp housing is OEM.

    ok, i should've clarified. the driver side headlight assembly was replaced with OEM spec aftermarket headlight assembly by the body shop that did the repair.

    The female three prong tab that locks in the light bulb must be ever so slightly different... the HID bulb from Elite XB35 will not lock, while the old 3Five hid bulb does slightly fit...

    2nd issue i'm having is that the Elite XB35 bulb + the connector for the bulb sticks out too far and I can't close the dust cover

    The ballast buzzing is due to where you have the ground wire on the chassis, move it to a different location, and that interfernce will go away.

    No idea about the fitment issues you are having though.

    So I didn't take a picture.... but the when the bulb is connected to the housing, the damn thing sticks out past the bulb cover....
    any tips? I can't be the only one having this issue....?

    So... I noticed that some people here have these types of covers...

    Yes the part number for that cover is a drill lol, that’s what people do when installing HID. Your bulbs should have some sort of rubber grommet to cover up the hole so it doesn’t attract moisture etc. Follow a few videos on YouTube on how to install HID and you’ll be fine.

    right.... the problem is, I had an old HID which fit fine with the headlight dust cover. The Morimoto XB35 HID kit has a longer light bulb + connector which causes the overall assembly to stick out past the dust cover, which can't be covered by the rubber grommet...

    In this case I would pull out and cut the grommet like split it to the middle, then just simply use clear silicone to seal it off. I do it to all of the dust caps and silicone will do just fine. Or you can buy just the grommet by itself so you can put it in the right spot since you mentioned it’s longer than what’s it suppose to be.

    So, I ended up calling my insurance and go over the repair bill.
    Turns out, the shop charged me for the OEM Kia headlight but bought a aftermarket. The shop replaced it with Genuine Kia part and the bulb will fit now.
    The only small issue I still have is that the bulb sticks out a bit, but that's manageable

    I'm actually having the same problem. On my optima it seems that the base/tube end of the projector sits very close to the triangle shaped mounting plate. As a result if the bulb base has thick plastic tabs or there is any plastic tube at the bulb base above the tabs then it will not be able to lock into the plate.

    I've had this happen with a few LED bulbs I've tried. On those I was able to remove the bulb base collar and grind it down. Today I tried to make an HID H11 bulb work and ended up breaking a mounting tab off... sigh..
    Will have to look more closely at H11 bulbs before I order next time..
