Does anyone know how to convert Rallye 1000 Spot Lights to LED?...................................cheers Ivan

+1 Wot 'e said. ^^^^
The problem with replacing the bulbs with LEDs in "reflector" type lights; headlights, spot lights and driving lights is that the relector and in most cases the lens flutes have been designed to work with an accurately posititioned pin-point light source. LEDs do not have this pin-point source, consequenntly the light from modified lights will not have the correct beam pattern to do the job as efficiently as a bulb.
Another problem you might encounter, especially with spotlights and driving lights is that the distance between the bulb-holder and the glass lens will probably not be deep enough to accommodate a direct LED replacement.
A third problem which might or might not be of interest, especially in colder weather is with a LED fitted, the heat (yes, heat) might not be enough to keep the driving lamp front from free of snow build up.
LEDs in other bulb-holders, say stop/tail, sidelights, reversing lights will generally present no problems.

With a thread titled "how to" I was expecting u to have the answer.
Why no fit an H2 replacement bulb that is an LED? I'm quite happy with the Osram Night Breaker bulbs I have fitted in my driving lamps, same with the head lamps.
sorry about the wording

I have H2 blub and holders in the rallye 1000 spots as per the attached pictures
I think I am p*****g in the wind as I have googled and googled but can't find any info, and the cost of new Rallye 4000 LED spots is away above me

I don't think, I know! If they ain't on the bay made by some little sweatshop in China then they probably ain't made.
So, it looks like a real grovelling letter to Santa tellin' him how you've been awfully good all year.

Been there with the searching for H2 LEDs after I fitted my headlamp bulbs, the driving lamps looked positively dim like the fogs that are still untouched, i suspect that LEDs in fog lamps even if they were available would give to much light flair in fog, maybe not as i haven't seen fog for years in my part of the world.

Thanks lads
again another bout of googling I think H2 LED bulb replacements do not exist, aye well will have to live with the dim yellow lights from the rallye spots for a little while longer
seen rallye 4000 LED spot lights on fleabay at 500 quid EACH

I don't see why you would have to put up with "dim yellow" lights when there are a whole range of H2 bulbs available, even if LEDs aren't.
Since these are additional driving lights and not your standard headlights, there's probably no actual requirement to limit the power, so maybe 100 watts instead of 55?
Then there's the choice of filling gas, Xenon tends to give a whiter light than Halogen, and don't forget the colour of the glass can also affect the colour of the light output.
If your spotlights are appreciably more yellow than they should be, then maybe you should be looking at the wiring to the lights to make sure that you're not losing too much by insufficient wire size or poor switching or earthing.

H2 bulbs shouldn't be yellow or dim. I'd question the feed voltage if they are. H2 halogen bulbs were the most powerful 55W bulbs available and still are.
Here's a few examples of other halogen bulbs available.
The H1 consumes 55 watts at 12.0V, and produces 1550 lumens ±15% when operated at 13.2 V.
H2 (55 W @ 12.0 V, 1820 lm @ 13.2 V)
H3 (55 W @ 12.0 V, 1450 lm ±15%)
H4 dip (55 W @ 12 V, 1350 Lm @13.2 V)
So you can see that the H2 is the most powerful standard halogen bulb out of the most common type used.
The H2 is no longer a current type, so getting anything other than a standard replacement, will be difficult.
So again I'd question the ability of the supply circuit if the H2 is dim or yellow. If fed with 13.2 V or more, it should be brilliant white and really bright.
Definitely much brighter than anything from the Night Breaker range.
As said. Anything LED simply won't work as a long range spot.

Bit of an update
1) I fitted full LED headlights, complete with DRL, not cheap china but good quality headlights, these where fitted a few weeks back.
2) the two rallye 1000 spot lights HAVE 100w bulbs and are wired in such away they have maximum voltage and the voltage is not a problem, these spots are mounted on the A bar.
Ok when I was driving the other night on LED main beam and with the spots on the light was brilliant no question about that, HOWEVER the spots as expected where not as WHITE as the LED HEADLIGHTS.
being someone who is OCD I wanted to see if I could convert the spot lights to something giving the same caliper of white as the LED Headlights, the description I wrote was tongue in cheek about dim yellow.
thank you all for the information

It depends on what colour temperature of your LED lights. Halogen bulbs normal output a colour temperature of 2,700K to 3,100K depending on make and gas fill.
Your LEDs could well be in a range from 3,600K to 6,000K. So by comparison, the halogens will look yellow. However halogen light is well saturated with light from the red spectrum. This is good as it gives you much better depth perception by comparison to monochromatic light offered by LED light sources.

Your LED headlights are almost certainly a very nasty shade of cool white, because almost all of them use really old out dated emitters that aren't used for anything else and typically are 6000-6500k or higher with really **** poor CRI.
The only ones I know of that are better are some extremely expense ones from KC Hilites that claim to use a modern XHP35 Cree LED. But I'm not sure you can get them for vehicles that drive on the left side of the road.
