I've just removed my LED H4s as I've been gifted a set of the latest laser headlight units from my mate who works for Osram, these laser units won't be available to the general public for a year or so but I'll be doing a full review here in a couple of weeks.
2 weeks is up, the suspense is too much for me

One thing I can tell you is an unexpected issue has been that of road sign reflection, while great care has been taken to resolve the problem of blinding oncoming drivers, something that wasn't anticipated was the driver and other road users following the vehicle with LARP technology may be blinded by the road signs illuminated by the LARP equipped vehicle.
The range of these H4 LARP units is in excess of 600 metres forward and is very well controlled to an extremely tight 2 metre point on the road ahead with close to zero spill outside on this, however if there is no self leveling feature used we have found there can be occasions where this intense point of light will strike a road sign as the vehicle moves over climbs and falls on the road.
As the reflected light from a road signs is completely uncontrolled (and uncontrollable) there is a very real risk to both the driver of the LARP equipped vehicle and anyone following that vehicle. This issue is overcome on production vehicles by the use of self leveling technology and reactive cameras that reduce the LARP output within a few milliseconds of identifying an oncoming light source, this could be an oncoming vehicle or the reflected light from a road sign.
I've witnessed LARP in action and without the self leveling feature or the reactive camera technology it can only be described as deadly dangerous for use on public roads, in fact the light output of LARP is so powerful and so intensely focused it is currently being assessed by the US military for use as a non-lethal weapon.
Trust me if you get caught in a LARP spotlight all you want to do is curl up in a ball with your back to the light source while you pray the LARP operator will either turn it off or move the ball of intense light away from your body, and all this at a range of half a kilometer!
For the time being I've returned to my excellent LED H4s as killing other road users and blinding myself with reflected light from road signs is something I'm keen to avoid, I have however fitted one of the experimental LARP H4s to my lamping rig so the local bunny population better go buy themselves some decent eye protection
Hi COG, I may of missed it, but what make are your LED's?
I intend to upgrade to mk3 lamps over winter, but as I've a MOT coming up next month and one of my bulbs has gone, I'll need to replace and so might as well put LED's in now with existing lamps.
I need to find out what's required for my rears too, as I think they look a worthwhile upgrade also while I'm at it.

I've been running LED H4s for almost three years now and would never go back to incandescent bulbs, the technology works better in projector rather than the reflector type headlights we have but even in reflector bowls they are a massive step up.
The technology is improving all the time, I upgraded my first set to the latest generation but that was a year or so ago now so things have moved on.
These days you should looking for an LED H4 that puts out 9000 lumens or more, you should also look for the new type that is 360 degree adjustable so you can tune your beam pattern perfectly to your reflector. Some have cooling fans but mine use a very efficient heat sink instead which is far more reliable than a fan that can fail.
Around £50 buys you the best of the latest generation, just be sure to order H4 as many sellers offer a choice and their default type may not be the H4 you need, usually you just select the type from a drop down.

Please note I have not tried the ones in the above link so I'm not recommending them, they have fans which I'm not keen on but they are 360 degree adjustable which in my opinion is a must have feature, there are literally hundreds of different makes of these LED headlight bulbs coming out of China, some are fantastic and others are total junk so it's pot luck trying to find the best on offer.
Whatever option you choose, you need to accept some headlight adjustment will be required or you'll be blinding other road users, adjust your headlights in the normal way then fine tune the LED chip position to suit your reflector bowls, to complete this last step you will need the latest 360 degree adjustable type as described above.

SORRY ??, a quick Google search and yes of course theirs some available, but would you know what type we require?
As I said before it's all here:https://www.pistonheads.com/gassing/topic.asp?h=0&...
JW Speaker make the best 7" projector headlights but there's more to it than that so you do really need to make the effort to read the full post or I'm just wasting time repeating myself.
Likewise did you click on the LED H4 link I provided above?
Here it is again if not...

Please be patient, this is revolutionary technology and in its H4 form is still being developed, there are issues and it is of course completely illegal to use on UK public roads

I believe their similar to the Philips ones I fitted to my RRC.
Their definitely an improvement, but I did change my lenses to the later style with a patterned reflector rather than the glass -seemingly that's another improvement to be had.
These type of bulbs are still going to be a country mile off the LED's power were talking about.

I modified the headlamp adjusters, the originals adjust from the front which is obviously no longer accessible, Central had slotted the other end of the adjusting screws, but it was difficult and fiddly to adjust as there's not much room to get a screwdriver in there without making the access hatch excessively large.
I used a selection of M5 screws, washers, nuts and wingnuts using some loctite and a lock nut with the wing nuts.
Bit of a thread revival. Toolbox, could you elaborate on how exactly you modified the adjusters, in laymans terms? As i need to do the same.I used a selection of M5 screws, washers, nuts and wingnuts using some loctite and a lock nut with the wing nuts.
Thanks in advance
Cad
Cad, have had a look at the bits left over and from the photos I had and this is my best guess....
I reckon the the middle post is non adjustable, whilst the other 2 are as shown above. I don't think there was any need for springs as the revised posts located the lamp bowl quite well. Have a look to see if this makes sense...if not I could probably whip off the ar h covers for a better look.
Cheers Pete

Thanks for that Pete. So basically it's a solid assembly and the washers allow it to be rotate? The thread lock I assume was put on both wing nuts lock nuts, but did you put some on the nyloc as a matter of course? Or not needed?
The one in the middle that isn't adjustable - I assume I don't need to change to this and just keep the original plastic clip type thing? Also keep the spring assy that is underneath?
Apologies for the q's but I've never actually adjusted a headlight in my life
Many thanks
