Looks like these (according to specs) fit 2004-2008 Jaguar X. They hook up to existing fog light wiring & then you need to run an ACC lead to power the driving lights portion.

The halo driving lights (DRL's) are (7,000 k) & the fogs are (6,000k).

 

I guess this might help, smfh

18W High Power LED Fog Lamps For Acura Ford Honda Subaru Nissan, etc

 

I run headlights and fogs same color temperature, 5K straight white. To me the miss matched light colors look like just that, miss matched. I like my road lights to look like shinning white diamonds. I have the HIDs with the ballasts for each bulb.

Are the LEDs straight plug in with no ballasts? I'd like to get rid of the ballasts. They weigh a few pounds and they have to be zip tied in place behind the lamp assembly.

These xenon LED fog lights are an excellent deal for those looking to replace their drab OEM fog lights. In my case, they were relatively easy to hook up - I just needed a bit of extra wiring for the DRL halo rings. The power connectors for the LED fog lights themselves connect directly to the OEM wiring, with one caveat: they aren't keyed, and the OEM wiring colors aren't red/black as one would expect so you may have to connect them then turn them on to get the polarity correct. The LED halo rings are not super bright but quite sufficient. The white fog lights themselves are very bright, but they are not projectors so they aren't focused. I would recommend some sort of protector like the Lamin-x films to cut down on the lens being sandblasted by small rocks. An overall good buy for the price. In my case, these LED fog lights cost less than replacing the OEM lights with OEM replacements and they're better than stock.
