Tim,

I did exactly what you suggest on a Golf GTI in 1990 for 100/90w bulbs and it worked a treat. The original bulbs and relays are still running!

Where did you mount the relays on the Scooby?

Another ex VW fan ? I had a golf 16 v Turbo with the cibie 7 inch grile conversion in, they were good till my bro tried them close up to a hedge @ about 125
Made a relay plate up out of a bit of alloy plate, bent and drilled to fit on the rear battery stay bar down behind the battery,bit of a squeze to get in but nice and dry,
have a good one

Hi Tim-H

I am interested in doing this on my MY00 wagon. Did you ever get round to producing a parts list and a "how to" instruction sheet? If so I would be very interested in getting my hands on it!

Tim-H

Sry mate , never got that far , no one seemed interested enough for me to spend that long typing ( if you typed this slow you would understand :-)
Have a look about on the web, I have seen instuctions and ready made kits, Also on the VW groups,
If you want to have a go at making one , I will help if I have time,
Have a good one
Tim

OllyK

That's OK Tim-H

May have a go at doing it myself, have found out some info. Would be helpful if you could supply a parts list though!

Cheers

StickyMicky

never thought about useing relays before
top idea!

Tim-H

What size`d bulbs are you lookin at useing olly ? do you want good ,very good , or right over the top ?

If a few people are interested I may make up a few kit`s in the new year, give me a shout if you anyone is, and I will sort out a price, (please don`t say your interested, if your not :-) I have enough on as it is :-)
Have a good one

Another thought , if you live in a city / built up area, the ajustment is fine , if you would prefer a bit more distance on your lights have a play with the horizontal ajuster, mine were set way into the kerb (presumably for the japs)wind them across a bit, mine have a flat beam pattern, with very little cutoff and a slight "hotspot" in the middle (still mot leagl) I used a mot beam-setter to do mine, but against a white wall at night will get close enough,
Have a good one

I have uprated the wiring and fitted relays for the headlights on both a 95WRX Wagon and M/Y 00 STi 6 Wagon. This was to allow me to run 130/90s in place of the Osram and Philips + 50%. I also tried two different sets of PIAA, 100/80 and another claiming 130w equivalent. I then got a set of General Electric (GE) +60% from Mac's Garage and concluded I had wasted my time uprating the wiring.
With the help of others who did not know which bulbs were in which vehicle we came to the following conclusions.
Best= GE+60%, about £19 including postage, next 130/90 but with the uprated wiring and relay. £12ish but illegal for road use. Then the Osra and Philips +50%. The PIAA were a major disappointment and for my eyes, especially the blue tinted ones.
In view of the above I would try the +60s on any future car and only then consider if it is necessary to uprate the wiring.

Tim, can we see some pictures of the finished job?

Hi Tim

I have got the Osram +50% in at the moment - fitted them at the weekend and they do make quite a difference. I need to get out on some proper unlit country lanes tonight to really acess the situation. If they are still crap then I would be interested in upgrading the wiring and going for some bigger bulbs, ought to get a volt meter out first to see how bad things are! Will keep you posted

Tim-H

I am having trouble posting long reply`s at the mo (bloody isdn) I will reply as soon as I have it sorted
How do I post pics
have a good one
Tim

OllyK

Tim - you need somewhere to host them then you link to them using "[ img ]" then the url to the image and finished off with a "[ /img ]" but without the quotes and spaces

You can e-mail them to me @ oliver.keeling@ramesys.com if you like and I'll bang them up on my domain space.

Cheers for the images Tim - and for all the rest of you...

Tim-H

pics sent , can`t see much , I will not be useing those fuse-holders again :-)
Have a good one
Tim

OllyK

Yup thanks for those - all posted an available!

I take it you had some problem with the fuse holders then?

TTFN

Clubscene

Nice job mate.

Tim-H

Thanks club :-)

No problem with the fuseholders (durite 30a waterproof in line)1 for each relay, they are just not the nicest of things with the orange wire already attached, and I am not a fan of the small blade fuse`s for large loads, they were all I could get on the day,
I am probably going to do a "MK 2" version in the new year, 6 x 70a relays useing 80a fusable links for each, it will be a bit over the top for most cars , but I want to see how much difference there is between good and silly :-)
80a fuseable links may seem over- rated but in a system like this, they are still the weakest link, if you get a fault on it it is normally very serious (tree`s, hedges,etc) and it will blow,
Have a good one
Tim
ps new ta card so I should be able to post now :-)

Lads, am I metering the bulbs correct - http://www.scoobynet.co.uk/bbs/threa...hreadid=285670

I get only around 10.23v on both high and low beam, but 14.2v at the Alternator.

Don't know if I should take the ground from the bulb or back to the battery/chassis.

I'd be inclined to do both, which will then give an indication of whether to put thicker gauge earths in too!

There will always be a voltdrop across a lamp because it acts as a resistor, even if it's put directly across the battery.
Just electrical theory, so I can't see any point in using a relay unless the resistance of the std wiring is high enough to cause a large voltdrop or the wiring is heating from being underrated.

If you read the 5th post down on page 1 of this thread, you will see that I stated if there wasn`t a significant DIFERENCE in the voltage at the lamp and at the battery, it wasn`t worth doing this conversion,
Please read the rest of this thread PROPERLY before you fall into your keyboard again,
have a good one

Tim,
Did you measure the voltage with the lamp connected and switched on or was it just on the back of the holder with the lamp removed?

Just interested

Dipster

Tim-H

Connected and switched on with engine running, the difference between the bulb voltage and the bat voltage is your drop, follow the link in an earlyer post and work out how much efficency you are loseing to see if its worth doing,
my estimate`s are:
less than 0.5v difference, don`t bother unless you have lots of time or money spare ,
1.0 v difference, it`s worth doing, there will be small noticeable difference but it`s not a must do,
1.5v difference, it`s worth doing, you will notice a difference,
2.0v and above, do it, you will want to clean my car on sundays for just suggesting it :-)
If you are thinking of useing higher wattage bulbs, I would say it is virtually essential to get the proper benifit from them, also your light-switch may melt if not done,(I have seen this happen)
Have a good one
Tim

Makes complete sence, thanks.
