Where do you guys place your ballasts?!

Once again with my crappy searching skills, I am in need of help from our community.

Where do you guys strap down/ 3M tape down your ballasts? Be it from HID low beam kits, AE kits, or HID fogs. Show photos if possible! Thanks guys

I have velcro'd mine to the small spine of plastic between the two bulbs inside the housing, otherwise the ballast was locking up the motor and causing it to jam. May vary bdepending on ballast sizes.

I'll try upload pictures later.

I did the same thing, and to clarify, he means the AE ballast is causing the adaptive headlight motor to jam. Mine did this for a sec then I moved them over and they were fine.

Beware of locating them externally as the wires could cause the headlight not to seal thus condensation or worse.

HID low beam ballast mounted

I had just had a horrible discovery with a low beam HID install I had done at a shop (won't list any names here, but it is in SoCal) and I previously had some Depo headlight issues so I removed the bumper myself to try and access the headlight to fix it but discovered that my ballasts were just dangling there.

First I fixed the adjustment on my Depo headlights and then I took on the mini project of properly mounting the ballasts to something stable.

1. You can see the before image (1st image) of the ballast just dangling behind the front bumper.

2. I used heavy duty Velcro tape I bought at Home depot.

3. Found a nice snug spot on the front bumper support beam right inside of the headlight plastic supports.

4. After having the ballasts firmly stuck onto the beam, I used an extended ziptie (put 2 together) and wrapped it to secure the ballast tighter so it would not break off from the Velcro.

5. Now my ballasts weren't flopping around while I drove.

Hope this was helpful, because this was the best location that worked out for me since the cables weren't long enough to reach anywhere else.

I'm another newbie needing help, has anyone heard or know why if I just swapped stock halogen headlights for depo projectors why my HID kit wouldn't work when hooked up to the car? Do I need to activate something with coding??
