which is best.ive fitted some hid's on my mates car but not seen or fitted any led's and how do they fit in the jag............is their something about unplugging the lights that stops the auto level or something.ive got a 2007 2.7d

hi

if your car has self leveling lights, then it already has hid lights

the self leveling was fitted to cars with hid lights and yes your right if your car has self leveling lights, if you unplug the headlight with the battery connected, the self leveling will stop working and can only be reset with jaguar software IDS/SDD

also any bulb or light fitted with a color over 4200k is illegal, if you get a awkward copper, but most mot station will pass anything, hid to be 100% legal should be self leveling and have headlight washer fitted, but I've fitted loads to cars and never had any issues, with mot's or police https://www.powerbulbs.com/blog/2013/09/are-blue-car-bulbs-legal

personally I prefer the HID's, but every one has there own preference , I don't think the LED's have the reliability yet, the led are fine, the power supply part is the weak link, also high power led's generate quite a bit of heat, if there not cooled, they fail, so that means either large daft heat sinks or tapes or fans are fitted on the back, you cant usually put the rear cover/grommet back on to seal the headlight either, so means your headlight is open to the elements, which end up get dirt inside and condensation

cheers

So if I need to change a bulb I need to disconnect the battery so I do upset the self levelling.

Also how do I know whether I have hid's  or not.i pick my new jag up tomorrow and that's something I've missed off my check list to date

So I'm guessing that if the bulb pops then the jag system may think the bulb has been removed and may need resetting anyway.could be a flaw
