[xj40] 1993 Headlight

XJ40
1

I want to switch from the single headlight to the dual (quad?). Is
this a plug and go or are there other mods needed? I searched the
archives and saw that some folks had asked the question, but didn’t
see answers. Any suggestions?–

Although my cars are both 1990, I’m sure they’re very similar. One
of mine has the single rectangular and the other car has the dual
round (which yes is a total of 4 bulbs).
I’ve not actually DONE the conversion, so hopefully someone with
more knowlege will amplify and correct me, but as I understand it,
in addition to the bulbs you’d also have to get the bezels that the
round bulbs go in, and change the light modules.
Suggestion: put an add on the JagXCHANGE Adverts to trade your
rectangular light components to someone wanting to convert to the
rectangular variety, and it may end up very inexpensive that way,
although you’ll probably have to paint the bezels to match the body
of your car.
My opinion: I really don’t know which looks >better–

Hey, part of my message got cut off! Anyways, here’s what I wanted
to say:
My opinion: I really don’t know which looks --better–
The rectangular setup is very classy and a great luxury look, while
the quad (round) is very old-school sporty.
I originally wanted to swap my quads for the rectangular variety,
but realized how great the sporty look is, and that it’s OK for my
wife’s and my Jags to have separate personalities. So we’re keeping
them the way they are! (although I’m considering switching to the
round, higher powered halogens recently mentioned on the list)–

You can change the bulb on the rectangular ones and put in a high
performance one. I did for about $8 and the difference was amazing.
The light follow the road as far as you can see. At least twice as
good as the old lights (relative comparison since they were not actually
compare side by side though you could change one side and check it
against the other, I did not think of it at the time).

ps, John is correct, I was talking about the brake pad sensor not the
ABS sensor. If I misspoke, my apology.

Can you give details of the higher performance bulbs and is
it a straight swap? My car has Euro-bricks… and could do
with more light up front.

Cheers

For higher performance bulbs in the stock lights, I am using the
newest Sylvania Silverstar bulbs. They are marketed as ‘‘high
performance halogen’’, and are a remarkable improvement.

Full normal daylight is about 5,400 K on a colour chart.

Standard High Intensity Discharge lighting on new vehicles is about
4,100 k on a colour chart

Sylvania Silverstar bulbs are about 4,000 k on the same chart.

Those weird looking ‘‘Cool Blue’’ bulbs that were all the rage the
last couple of years are about 3,500 k on the same chart.

Standard Halogen bulbs are about 3,200 k on the colour chart.

The old incandescent lights are about 2,800 k on the colour chart.

The new Silverstar bulbs are almost as white as the newest High
Intensity Discharge lighting systems on the newest cars, and the
Silverstar bulbs seem to me to be much brighter than the normal
Halogen bulbs as well. The old normal Halogen bulbs make a light
that looks really yellow in comparison, the Silverstar bulbs make
a really bright white light.

The bulbs are a straight swap. Straight direct replacement for the
stock Halogen bulbs, I have four of the Silverstar bulbs in my 92
Sovereign, and I am also using them in all my other vehicles.
Highly recomended.

I have the Sylvania Silverstars in every one of my cars that uses a
bulb (except for an Expedition that has Sylvania Cool Blues), and
they are indeed a VAST improvement over ordinary halogens.

The Sylvania Cool Blues are a good bulb as well, and an excellent
value for the money. The name is somewhat misleading as they
absorb blue light rather than emit it, so if you want the boy racer
blue tint, the cool blues are not the way to go. They put out a
bright white light that is very close to the Silverstars.
