So the halogen foglight on the Discovery has always bothered me, especially when the AFS Bi-Xenon lights I have are ~5500k in color temperature. https://www.theretrofitsource.com/land-rover-morimoto-xb-led.html I was previously familiar with The Retrofit Source and Morimoto Products, and was intrigued with the Land Rover XB LED fog lights. These lights are plug and play, and took less than 5 minutes each to install. They will also fit on other Land Rover and Range Rovers (Replaces LR Parts # LR001587, LR057400) The color temperature is 5500k, and output is claimed at 1,200 lumens per light. Also has a 10 year warranty! Anyways, onto the install! Like I said, this was very straight forward. I only looked up how to uninstall the old fog lamps, as I had no idea. First, just a small comparison of the halogen fog light vs the LED fog light. Output comparison Each fog light comes in its own individual box. First thing you need to do is pry the plastic cover off your front bumper. This was relativly painless for me. I carefully stuck my fingernails under the cover and popped it off. You can also use a plastic trim tool (wrapped in a soft cloth to not scrape your paint) to remove this cover. The clips are metal and I did not break any. You need a Torx T-20 bit/screwdriver to remove the OEM foglights. I was expecting 4 Torx screws per foglight, but was greeted with only 3... Maybe my car was made on a Friday. I rotated the light assembly inside the housing to first remove the bulb/wire from the fog light, remove the fog light, and then unplug the bulb. The clips are pretty standard. The OEM lightbulb comes out with a counterclockwise rotation. Clips weren't too bad to get off. You can pry both off at once and go for it, or easily pry both off a little and pull the entire bulb out at once. If you intend to reuse these bulbs, don't get your finger oils on them. Package Contents The rubber protectors need to come off the contacts on the end of the wires. Before inserting the contacts into the plug, make sure you're putting the positive/negative on the correct side. The blue is positive (red), black is negative. On the Morimoto provided plug, there is a little bump on the top. Make sure this is lined up properly, or else you be reversed when you go to install it. The plug only goes in one way. Bump/tab on top of the connector with the positive wire on the right side. The new Morimoto housing is complete plug and play. It just slides right into the little slots. (Notice only 3 of the holes for the torx have been used?!) Plug in, and slide it in, and screw it in. I elected to use the OEM torx screws, and did not use the provided bolts that came with the kit. They seemed huge and I didn't want to enlarge the OEM holes. (This may be different for other Land Rovers, I'm not sure. But the LR4 I did not use them.) All that's left is putting the cover back on. Before snapping the bumper cover back on, I'd recommend testing the lights.
