Rear Lamp needed sought with mounting holes 100mm wide at centre line?

[McCabe-Thiele (Ted)]

Having recently bought a rear number plate bracket for my UK spec 500 rear mudguard I have found the rear mounting spacing is too wide for the standard  for 400/500 Stanley HM11RC lamp unit. The 4 mounting points fit the rear fender perfectly so looks as if its from a different model.
The 400/500 has mounting points some 94/95 mm apart I need a lamp that has 100 mm spacing.

I assume there must be a similar light with the wider fitting can anyone help with the model or part number I need please?

You have a us 500K2 bracket there and the light that fits will be the large one with 4 screws holding the lens on like on the 550K3 and the late 750

Is that the lamp that looks huge that nobody likes then?

Yes Ted, it's that big it looks like a barn door bolted on the back end of the bike 😊😊😊

This one on Ebay, however due to it being a USA bracket and thus chrome instead of black you must also be aware that the number plate holder is smaller than ours. It can mean the screws come through right where the letters are etc

Ted, do you need the whole lamp, ie chrome and lens. I have spare lens in great nick but the chrome has been painter over.
If you think it will do I can put some pics up in the am.

DS replica is only £17.94 plus VAT at the moment looking at a LED complete unit as an alternative.
It will need a little creative cutting but this was cheap enough to have a go with.

Okay I need to sort out the "sandwich" a tad better as the side view is not acceptable - but the lamp will fit!

In an ideal world a nice block of aluminium would sort out the gap between the LED lamp & the rear number plate mounting.  Aside from the cost it's a lot of cutting that would be far from perfect.

Looking for ideas such as a plastic infill block that's easier to cut. Any ideas welcome to fill the gap properly.

I nicely shaped hardwood spacer?

Or get someone to 3D print something.

Get some acrylic Perspex in black Ted, something like 10mm, fairly easy to cut and work, used to do it with lots of perspex. A few recesses for the mounting rubbers and you would be able to see anything after. Looks simple enough to do.

I used to do loads of LED conversions for cars about 10 years ago, I'd convert the dash from normal capless bulbs to LEDs, typical conversion was around 100-150 LEDs as they don't illuminate the same as normal bulbs, the beam angle is very narrow so where 1 bulb would work ok you'd need 10 or so LEDs to do the same but it did mean for instance I could get the needles to shine red but the clocks to shine blue. I was thinking of doing an LED conversion in a normal Honda rear light but fitting around 30-50 LEDs in there instead, looks standard until it lights up.

On another note, I fitted an RD250 rear light to mine back in the day, 2 bulbs instead of one so if the bulb blew you weren't left with no rear light as you had the other bulb. Can't tell you the number of times I had to lift the rear brake light switch out of it's bracket so the brake light was permanently lit as the rear light had blown and I needed to get home in the dark. Far better than no light at all and stopped the Police pulling you for having no rear light. The Yamaha light really suited the bike.

Your post reminded me that on  many Mercs there's is a built in back up spare bulb in the tail lights. The dash bulb checker would illuminate - owners thought it was a false message as they could see both lights were still working.

Hi Ted

I do allot of 3d printing for the RDLC lads so happy to print something in black ABS if I have a drawing of what you need so I can model up something then print

Thanks for you offer Alan, if my attempt at fashioning a small piece of black acrylic sheet fails I will be in touch.

How is the spare big bore 400 engine project progressing?

[allankelly1]

Hi Ted

Big bore is on hold at the moment as have decided to commit all spare funds to my Tigcraft project to see how far I can progress it in 2023 as its a real money pit as got frame changes to be done by my local frame guy in March, and then a set of bespoke exhausts to be fabricated by Andy over at 2T engineering later in the year

Also in the middle of sourcing all the engine parts so I can complete the 350cc engine comprising of a LC bottom end with A/C barrels and heads and as we know LC stuff is all crazy prices
