Today I had my K40 Laser Defuser installed...relatively easy installation if you have the proper tools and patience to remove panels slowly. This defuser loudly signals when your car is shot with laser and defuses it so there is no readout from your vehicle. It comes with a red LED as well, which blinks when you're hit with laser. It has a ton of range as well...enough to slow down and not get caught. K40 even lays your ticket if you indeed get one. We mounted the red LED in the top middle of the gauge cluster...you can barely notice it and it looks OEM. The word runs right along with the hood release wire, so the engine bay looks seamless as well. Here are some pics. Here's the box it comes in. Run wire along hood release. Use small zip ties and hide the wire under hood release wire...can't even see it when it's done. Drill hole into top of bezel. Use the clip because it marks a center point. Top home must be made larger to drop LED in from top. You can insert it through bottom of bezel, but more of the light would stick out. Hot glue wire to top side of bezel. I also made a notch using a file in the clip to run the wire so it did not interfere with snapping the bezel back in place. Add two dabs of black colored hot glue on the wire to keep it neat. Here a look at LED once installed. It's bright when it lights up, but you barely see it when it's not lit. Panels removed to run wiring and install the speaker for the warning chime. Everything mounts right to the aluminum plate you see there, that's already in the car. The speaker is plenty loud, even being mounted behind the dash panel. Close up with cluster removed. Cluster is only held in with clips. Remove carefully, so as not to break any clips. Another view of where we put LED. Plate frame with mount for defuser sensor installed. Looks like an EZ Pass, to be honest. Enjoy and drive safely!
