Just the nature of LED"s, Wilco, not your aging eyes.  I had a similar problem with the brake light on my sidecar.  Rick (Motorrad Elektirik) sold me a bulb that was technically supposed to be brighter than the conventional one, but it was a really bright pinpoint.  The regular bulb actually looked more visible because it lit up the entire red reflector.
Maybe in the future they'll figure out a way for the LEDs to be a direct drop in and look the same as conventional but for now I think we have to experiment.  Getting better though....

Well, Lights are devised to be in a reflector and this is designed to use as much light as possible.
As the tail lamp on our bikes is supposed to hold a filament bulb, the reflector is designed as such. If you put a bulb that ahs a very narrow angle of emission, the reflector is defeated and the tail light is not bright enough. This is why it is difficult to find a proper LED replacement for H4 bulbs I have found one and the LED are exactly positioned where the filament of the bulb is... So I think it needs a lot of engineering to make it right (or start afresh with a new tail light design powered by LED technology)

Your speedo is 5+ times brighter than mine with the present 194 LED...…….  hopefully the ones coming in tomorr0ow are brighter

We have success!!! The new LED's are brighter and I can see the speedo.  The LED's that worked are pictured below. They were a tight squeeze going in the hole. I had to try two as the first one I would have had to "force".

Thanks guys for all your input!!

Hi,

The "5 X brighter" is a photo of my speedo. The tachometer has the standard incandescent bulb. Thanks for posting it as I would have had to find the original which is no longer on my computer!
