There are several things about the Jag that are distinctly British, and are wonderful for it. I like the manual that instructs about using 95 or 98 Octane fuel (the UK norms) whereas the best you can buy commonly in the USis 93 or 94 (superspecial ultra premium so rareified and unavailable you wouldn't believe how difficult it is for us to make it, soget down on your knees and pray for a good day at the refineries,y'all).

The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel through a specific test engine with a variable compression ratio under controlled conditions, and comparing these results with those for mixtures of isooctane and n-heptane.
There is another type of octane rating, called Motor Octane Number (MON) or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally fuel specifications require both a minimum RON and a minimum MON.
In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-95 (regular) in Europe.
The octane rating may also be a "trade name", with the actual figure being higher than the nominal rating.[citation needed]
It is possible for a fuel to have a RON greater than 100, because isooctane is not the most knock-resistant substance available. Racing fuels, straight ethanol, Avgas and liquified petroleum gas (LPG) typically have octane ratings of 110 or significantly higher - ethanol's RON is 129 (MON 102, AKI 116). Typical "octane booster" additives include tetra-ethyl lead and toluene. Tetra-ethyl lead is easily decomposed to its component radicals, which react with the radicals from the fuel and oxygen that would start the combustion, thereby delaying ignition.
the point of all this is that our north american premium (91avg method) is equivalent to the premium in UK and europe. We can get north american ultra premium (94 avg method) at some stations. that would be equivalent to 98 or 99 in Europe.

Hi Guys,
thats a full week near as dammit, and about 1500 miles on the Saab, mostly with dipped beam on constantly due to poor visibility and extreme rain. The X? Well, she's been back and forth probably covered around 200 miles, mostly at night and early morning, as the wife works night shift, so again, mostly with dipped beam the whole time.
No problems, just plenty of light!........lol

Hi Jim C
When you installed those 80W / 100W bulbs, did you install the plastic cover, or removed it totally?
If you installed that cover, did you made any extra breathing holes to make sure that the light does not heat up too much?
Was those Sportzblue 80W / 100W bulbs from Ring Automotive?
Did you connect those bulbs just straight to cars original connectors, or did you install relays and took wake-up power from cars original wires?

Hi all,
there's been a few issues with lights recently, one of which I posted myself.
Just earlier today I fitted 80w / 100w Sportzblue bulbs and man...WHAT a difference. I can actually see in the dark whether I am driving the Saab or the Jag. It really is like night and day. I got them fitted in the dipped / full beam and also foglights and supplemented them with PIAA blue bulbs for the sidelights which give amodern HID lookingblue tinge. Cost for both cars was £93 which was pretty reasonable I thought.
To those with concerns, I will post if there are any problems with wiring loom, blown bulbs etc but I don't expect any. The wife has just called after arriving at work and is very pleased.....
I look forward to her gettin home![Wink](https://www.jaguarforums.com/forum/images/smilies/wink.gif)

I have also fitted the rear park assist I mentioned a week or so ago and it works great too....so its all good.
Clear side repeaters fitted as well with orange bulbs that look much better than the stock orange repeaters and a handsfree car kit to round it off...........so I've been busy as you can see.
Next on the hitlist I think will be cruise control upgrade and for sure EBC grooved dimpled rotors married up with redstuff pads for serious stopping power. Makes sense though to get the good outta the existing discs n pads so that may be a little while yet.
Cheers

Hey Delta, I've not had one single reaction from other drivers as to dazzling them etc and certainly not been flashed. They are set correctly and just a brighter whiter more usable light with a slight bluish tinge, not unlike HID's.
I certainly never changed them in the Jag before it went in for MOT and had no problems.
I recently completed this self same upgrade on my 07 plate Audi A6. I've included a link below for you to check out. Compare the background dtreet lighting to my new improved headlights and notice the difference. Before my headlights were very similar to the light emitted from the street lamps

Sorry guys - I've cut n pasted the info below for you
I've been replacing my interior lights recently with leds.....beautiful cool bright white light with a slight bluish tinge ( see my interior light led thread )
As part of this I wanted to upgrade the headlights, foglights etc too. I seriously thought about an HID kit but as my car doesn't have projector headlamps I decided against it ( at present anyway )
I went for Sportzblue by Ring automotive and bought from Autobulbs direct.
I upgraded the dipped beams to 80w with H7, the main beam to 80w with H1 and the foglights to 80w with H7 also. At the same time I upgraded the 501 sidelights with the bluish tinge for the HID look.
Please see pics below.........
A seriously marked improvement as I knew they would be. I compared them to my wifes Passat yellow / dull tired lookin standard bulbs. I did this upgrade beofre on my Jag X type so I knew it'd work well
well chuffed!

Ooops, forgot the Led upgrade to the rear number plate lights.
Pic 1 view from ground level front
Pic 2+3 showing the leds currently fitted to the rear number plates.
The rear is now bather is extreme bright white light again with the slight bluish tinge and actually casts a line on the ground - very cool looking.
Notice the yellowish street lighting in the background as a reference point

I was just researching lighting options for my 05 x since I'll be keeping it through another winter. I was thinking of replacing the DRL (daytime running lights, aka front parking lights) with white LEDs, along with LEDs for the brakes lights etc. Anyone have any issues with LEDs? How about turn signals, I read some cars have fast blinking issues or trigger dash errors when they swap to LEDs because of the low current.
Still trying to decide on 55w or 80w lows. What's the stock wattage for the high's and fogs?
Thanks, Joe
