Installing a HID Kit Without A HID Bulb Holder

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.
