How to Install HID Xenon Headlights on 2007 Lexus IS [Video]
Here you will find instruction on how to install such a system on a 2007 Lexus IS, but the creator of the video tutorial ansures that his method applies to every IS model since 2006.
So, you will need a compatible Xenon headlight kit, a drill with a Unibit or a hole saw, a wrench with extension arm, a 10 mm bit, zip ties and some screwdrivers.
Before starting, disconnect the car’s battery and make sure the cable won’t touch the battery on the rest of the process. Next, unscrew the plastic side panels from under the hood to gain access to the parts underneath them.
After that, you have to remove the airbox from the left side and the ram air. Then prepare the Xenon ballast and fit it on the car as seen in the video. Next you will have to drill some holes in the headlamps casings in order to fit the corresponding wires to the light bulbs.
Now connect everything as seen, reconnect the battery, test the headlights and if ok you can put back everything you have dismantled.
