Installing a HID Kit Without A HID Bulb Holder

We get asked all the time about installing a hid kit when the vehicle has a H7 Bulb holder, these can be found on many cars including some Ford Fiestas, Mercedes A Class, Mercedes C Class and many more.

We used to sell a modified version of this that was split along one side and allowed us to quickly and easily pass the HID Bulb wiring through it, the problem was with the slit in the bulb holder it lost its rigidity and made installation difficult. We stopped selling them and using them ourselves and instead devised a way to use the original bulb holder.

Here's how.

When you first take the H7 bulb and bulb holder out of the headlight this is what it looks like.

Simply pull the H7 Bulb out of its socket and you will be left with just the Bulb Holder and the original socket.

Prise the Bulb holder from the sides away from the socket, you should then be left with just the H7 Bulb Holder.

Next take the H7 Xenon HID Bulbs.

Untie any of the cable ties so the wiring is laid out like so.

Take the wiring with the two spades on the end and gently pull them through the rubber grommet.

With that done now take the round connector still connected the the H7 HID Bulbs and squeeze it through the H7 Bulb Holder.

Once you have the round socket of the HID Bulb through the hole, place the smaller connector through too.

Feed the Bulb Holder down the wiring and fold the rubber grommet and post that through as well.

Now feed the spade connectors back through the holes in the rubber grommet.

Now your left with the H7 Bulb Holder and the H7 HID Bulb ready to install.

Take the plastic cover off the HID Bulb and align the Bulb Holder correctly.

Install the H7 HID Bulb and the original holder into the headlight, checking the fit from the front of the headlight.

Fitting the rest of the HID Kit remains the same.
