thebrookster Posted August 5 Posted August 5 I'm certainly interested to see how you fare with these. One of my big bugbears with modern lights is the lack of care taken over beam spread, so I'm rather chuffed you have taken the time to check this! Kudos to you!
PaulAA Posted August 5 Posted August 5 Mike Interesting - I tried swapping to Philips H4 LED lamps in standard Lucas curved and prismed 7" lens on the TR6 a couple of years ago, and was roundly disappointed. The vertical and horizontal beam spread in both main and dipped was random to the point that it was not possible to distinguish between the two, except that main created slightly more glare for oncoming drivers. I refitted the lamps several times, without improvement. Obviously, the LED lamp position works less efficiently with the standard reflector and prisming, and blind spots are created by the diode holder. The better solution would be to use a sealed beam LED unit, but I've swapped back to halogen and am much happier. Also, the 'cold white' of LED (I think they're 6500 Kelvin or more) gives it a restomod appearance and, for me, the warm white of halogen works better aesthetically. Paul
Gt64fun Posted August 5 Posted August 5 I have Cibie H180s with Philips Visionplus H4 halogen bulbs, which are switched via a pair of relays. Beam pattern and intensity on dipped and on main beam are awesome! The Cibies are expensive but worth it in my opinion. Ian
mpbarrett Posted August 6 Author Posted August 6 Drove the car at in the dark last night. The new LED bulbs are very good and very bright. Beam pattern good but the difference between full and dipped is very marked, with the dipped too low. I had noticed this when I had halogens (Osram night breaker) in them but it seems much more marked with the LED bulbs. I guess the light source, LED chip, is in a slightly difference position and size. Will have a look at what type of lens I have in the car! Cibie are a bit expensive!

Set the dip to the correct beam pattern cut-off and let the main beam do its own thing. The main beam will not be on to bother on-coming traffic - will they !! Â Roger

mpbarrett Posted September 8 Author Posted September 8 going back to the Headlights fitted new lens and the difference between full and dip was much better. Fitted LEDs to the sidelights and indicators. Needed to clean and paint the reflectors behind the lens and now much better and brighter. Â Â
mpbarrett Posted September 8 Author Posted September 8 (edited) Just back from the 10CR. A very long route this time with most days being 8 or 9 hours driving. Myself and Jane (who navigated but didnt drive) we cut lots out of the route but still did more motorway driving than we wanted to do. The problem is that this years 10CR went to south of France; its a long way so you need to do a lot of driving... The car had lots of small issues, none were show stoppers; The night before I noticed one of the 'Welch' plugs on the 3 rail gearbox had gone missing and explained why we had some much oil around the gearbox, only noticed when I was looking from the engine compartment. Temporary fix was an ali plate and lots of sealant. Speedo broke before we got to Dover, Horn stopped working, Electric fan connection fell off, Small petrol leak from a hose under the car (that I had missed when I worked on the car before we went on the trip). Solved by a new clamp on the hose but noted the pipe is looking rusty. At least it the return flow so not under any pressure. Biggest problem was a new issue, jumping out of 3rd gear when on over run, This was a real problem going down some of the passes. Need to think about whats causing this to happen.... Good bit, the baro correction worked well (leaning the mixture as the barometric pressure dropped), tweaked after the first pass (2000m) and we had full power up the next pass (2600M). But the idle was all over the place going from rich to lean. I adjusted the tickover to make it higher but off the mountains this meant it was running lean and started to get hot, probably need to tweak the map on higher revs at tickover to solve this. The most worrying were noises from the O/S rear drive bearing this got worse and started to make a grinding sound on left hand corners. I had checked the bearing before hand but could not find and play in it so this will need looking at. But we have done over 2000 miles on a lot of nice driving roads, a few very high passes and lots of motorways. The car seems happy at 75 but will easily go to 85 so it will keep up with most of the traffic. Weather was 'interesting' with some amazing thunderstorms and torrential rain on the Italian motorways.... We stayed in some nice places and had some good food and banter so a good trip!

PeteStupps Posted September 8 Posted September 8 Well done Mike, good to read you got around despite the niggles and issues. Nothing useful to suggest on the gearbox but will be interested to hear other's opinions on a likely cause. Something to do with the synchro hub maybe?Â
Hamish Posted September 9 Posted September 9 Always impressed with you guys that do these long trips in your cars. I’m concerned with the speed events I do ! And they add up to 7 miles at a good event with a few runs. (SHELSLEY is more like 4 !) With probably an accumulated 1hour + idling. Much respect 1
Escadrille Ecosse Posted September 9 Posted September 9 (edited) Good run. Might be the welch plug and 3rd gear are related. Check detents on the selectors and as Pete says travel on the synchro hub for detents there too. And dreaded split mainshaft spacers. Â Edited September 9 by Escadrille Ecosse

Partly because it goes to a completely different part of the map at idle due to the pressure change I think….. i was and still am planning to do some altitude tweakery but a bit nonplussed today as going over the Grand St Bernard today without altitude correction caused no problems. It even idled at the top (albeit very slowly) which it’s not done before. I can only assume that 8% authority on the EGO correct (is enough for it to self correct.Â
Nick Jones Posted September 9 Posted September 9 Sounds like you had a good run though. Assume you were mostly off the peage? It’s fearsome expensive these days. Getting back from Grenoble in reasonable time without spending a fortune is going to be a challenge!

The 10CR is an expensive trip these days... I wished we had got a Tag as some of the machine were unreachable from the Herald if you have short arms!
Nick Jones Posted September 10 Posted September 10 Actually going to try and use Ellis’s route from 2013 for our run north at the end (but in reverse and avoiding Reims). We’ll see - peage will always be minutes away if it’s taking unbearably long. Big day planned for tomorrow from Courmeyeur to La Mure involving several high passes…. The laptop is charged… 1
