Dear All,

With regards to brightness, this is the comparison I made with an odd 26/8W tail light bulb (it was intended to be a comparison with a standard 21/5W filament bulb, but only after taking the photos did I realise it was an odd bulb I'd picked out!). My intention when designing the LED light board was to produce something that gave the equivalent light output to a standard filament bulb but with much lower current draw (for my old bike) and also constant illumination across voltage fluctuations (i.e. low battery, at tick-over etc). There are more pictures here if you're interested: http://www.matchlessclueless.com/led...d-rear-lights/. As has already been mentioned, my approach was quality rather than quantity and more LEDs are not necessarily better!



Please take the above photo with a pinch of salt - it is almost impossible to photograph a bright light on a dark background! However I think it does show the relative brightness of the LED (top) versus 26/8W filament bulb (bottom) with both tail and stop functions lit. Things to note are that the LED is slightly brighter, has a larger area of illumination thanks to 10 'brightspots' versus one of the bulb, and less light wasted out to the sides where it is not required. The number plate illumination of the top LED light is somewhat drowned out by the 'wasted' light from the bottom bulb, but in practice it is more than sufficient to provide full illumination to the whole rear number plate.

Once again, thank you for your interest and really pleased to see that these lights will now be finding their way on to some rather nice Triumphs around the world.

Please feel free to PM me with any questions.

Kind regards, James

I use the Lucas adapter kit from Maund. It mounts the lamp using the original holes in the fender and uses the stock vibration damping grommets. Also it positions the lamp at a nice perky angle and not tilting downwards.

Its a beautiful job. You make these adapter plates yourself yes?

I've seen the adapter plate before and thought what a great idea. My light was one of those with integrated turn signals from NewBonneville. It came attached to a stock rear fender from Fleabay for a very reasonable price. However those at NewBonneville who had drilled the light case to take the turn signals had attached them in such a way as to poke upward and backward, and frankly they looked stupid.

So the first thing I did was to order a new light unit, fit the turn signals with LEDs and relocate them. I also fitted the light with one of James' LED boards.

My light doesn't hang down, niether does it sit at a 'perky' angle like yours, its more or less straight. I did the drilling on the new light case and it uses the stock mounting grommets just like the NewBonneville one, except that I took more care about it.

I had intended to get one of your adapter plates, but I have a Triumph grab rail which has a dresser rail running around the back of the seat and there is less than 1/4 inch of clearance between the dresser rail and the light casing. If I fitted the adapter plate the dresser rail would hit the light fitting. I think its a shame that the adapter plate can't have some adjustment, because I would like to raise the angle of the light just a little bit.

I must say, this forum is an incredible place. We now have D9 brackets, the Maund light adapter plate, James from the Matchless forum making LED boards, and I am working on a turn signal controller, a bit like the Signal Minder. The results will be put onto the forum when its finished.

I just got the MatchlessClueless LED fixture, can't wait to install it. en7jos is also very good with communication and service. Thanks!

Hi James,

Would you be interested in producing an LED rear light for the factory triumph rear light?. I'm sure you'd have a large market, and I could probably sort out a rear light unit for you to examine.

Hi Rob and all,

Yes, I'd be more than happy to look into making up an LED light board for the original Triumph rear light if you think that this would be of interest to other owners.

I would of course need one of the lights to work with. So if you have one available that I could lend and are prepared to post it to me in Hong Kong, then I'll return it with a nice new LED light board fitted! The only thing I can't guaruntee is how long it might take as I'm also in the process of making up some boards for other classic bikes.

Regards (and happy new year!), James

I've sent you a PM Rob, look forward to hearing from you!

Is an LED light board for the original type lamps something that anyone else would be interested in?

Regards, James

I'm sure that there are some who would like to convert to LED without the extra hassle of changing the light unit and wiring.

This has already been done by one member on the stock light unit:
