The Monday Club have tried various
conversions to the headlights of our cars with varying degrees of
success. 136-8779 has received a BMW upgrade with Xenon bulbs, which has
been good, and Chris Miller has added Xenon's and a re-wire to 136-8801
to get rid of any low voltage problems due to poor connections, which
gave great results on our Istanbul trip.
There is the "Double Dipped" headlights, but this can be more than the original alternator and wiring
(especially the headlight switch) can handle.
I had gone to
double dipped, using 4 combined dipped/main headlight units, rewiring
with heavy duty relays, and a second "Light" switch on the dash board.
Steve Payne has
tried out one of the modern HID (High Intensity Discharge) systems,
which is basically a high voltage discharge system similar to that used
in cinema projectors, etc, which are fantastic. The dipped and
main beam outputs are as good as any modern systems in cars I have
tried.
Here is Steve's
story.
"The reason I did it was I found
the standard headlights only adequate especially living in the
countryside. I had tried those Xenon bulbs that are readily available
but to be honest there was hardly any improvement.
The pictures hardly do it justice, if you stand in front of the lights
when they are on they turn blue jeans white and if you look at them
directly you get spots in your eyes.
HID on the Left
The down side of this conversion, it is not a cheap conversion, I am not
sure of the legality of this and the electrics need to be in good
condition due to the high starting load.
I bought 4 new headlight units, pods and the 2 HID kits.
The
Discharge Generators
I have been told by a motor
mechanic friend when these are fitted to a new car they must have self
adjusting headlights to be legal, as my MOT is not until next year I
will have to see but if they are adjusted correctly I think it should be
OK.
New
headlight units
When they start up they draw twice
the amps that they use while on, just like a fluorescent tube. They use
the same amount of amps as standard lights once warmed up.
When you switch on to main beam there is a slight delay the first time
because the arc has to be generated.
The finished Job
Since I fitted them I have done about 60 miles at night, I have not been
flashed at so oncoming traffic must fine them OK. Driving at night is
much easier and I find I do not use main beam as much due to the dip
beam being so good.
I have been contemplating this conversion for a while and even though
expensive is worth every penny if you drive at night.
Steve was
concerned that the HID lights may not pass an MOT, but since fitting his
car has passed 2 MOT tests. The tester said the although they were "not
right", there was no legal reason to fail them as they passed the light
meter test.
He chose the "4300k"
bulbs which give the greatest light output (for a standard setup you
will need the "H1" type bulb).
As I had already done a double dipped
system, and given the cost of the units Steve had fitted I didn't bother
doing anything about it until a couple of weeks ago Steve sent me a link
to a E-Bay page where they were doing HID units for $25, complete. This
meant I could buy 2 sets for $50, which with shipping and import duty
would still only be about £70!!
I contacted the seller to see if he did H4
versions as Steve had fitted H1 which is the separate dipped/main units.
H4 is the combined dipped/main version. The seller said he did, but they
were $8 extra. Not a deal breaker :0)
Before you start mark up
each headlight and each headlight pod so the go back in the same place
to minimise the amount of adjustment required!
I ordered them and they duly turned up, and
looked decent kit.
The kits
comprised the discharge unit, which generates the high voltage
A relay which
switches between dipped and main beams
The letter "I" on the left hand relay is for
"Inner Headlights"
These relays had
sockets which connected to the existing headlight bulb plug so when you
switch from dipped to main it activated the relay
The H4 HID bulbs and plugs
And brackets for securing the
discharge units, which I mounted behind the splash plates under the
wings (the leads from the discharge units are quite short so they need
to be near the headlights)
I re-sued the
heavy duty relays I had previously fitted
And the additional light switch on the dash
You need to enlarge the hole in the headlight pod
to get the larger plugs through, so I sealed them with silicon
afterwards to stop water getting in.
