That looks snazzy I bet it doesn't look as good in my corroded dented clocks.

The photo doesn’t do it justice. It looks even better in the flesh

Nice John
Did you find ones that fit in the existing holders or did you do some adaptation

Source would be a help

Nice, and saves some Watts here and there.

The only issue's with led's is their colour temperature. The colour temperature of the original bulbs is around  2200 to 2700 Kelvin, the modern white led's have generally a colour temperature around 4000 to 5000, and sometimes 6000 Kelvin. In plain English, way to white / blueish. For me, one of the charms of these bikes is the old fashion "warm" white colour of the face plates. The warm white gives me that retro-look when riding it. Next to that, most modern LED's are way too bright.

I was also looking for replacement for my clock lights (for my 1966 CB450) and tried a few before I was satisfied with the result. If one can find LED's with a colour temperature of 2200 to 2700 K for the faceplates you're done, but in most cases, the colour temperature is not mentioned on web-sites or shops (except for head lights and indoor LED replacements).

I found that yellow LED's give almost the same warm light as the old bulbs did. For the neutral I choose amber (if you're  buying green, it's just too green), and orange for the winker indication, or in case of my bomber, for the hi-light.

I like that, very cool  8).
Details how you did it please Jon and and materials/suppliers.  I'd like to modify the CB250RS clock lighting if possible.

Sorry, I can’t remember where I bought them, online somewhere, and yes they were just a straight swap for the originals.

How did you wire the indicator light as the indicators change polarity left and right. Therefore the LED should only work on one side as it's a diode that only allows current in one direction?

I’ve only put LED lamps in the speedo and rev counter

If you wire in two LEDS back to back they'll work in both directions.
Where's that 10mm socket got to?

O yeah, why didnt I think of that. Just getting the drill out to make the hole twice the size. ;D ;D

Roy I must be really dumb but looking at the 500 wiring diagram I don’t for the life of me see how they change polarity can you expand

The bulbs are a BA9S fitting just look for BA9S LED BULBS on flea bay, there are loads 👍👍

Perhaps the 500 is wired differently? Would be interesting to test the 500 with a multimeter to see if they do change polarity. The usual way to wire LED's is with a fused direct live feeding into 2* 12v relays, then the indicator connectors 1 to each relay switching the output to the led lamp. A lot of work to just change an indicator repeater bulb to LED. I took mine back out again and re-fitted a standard bulb. Not actually sure why they reverse polarity, like you I couldn't understand from the wiring diagram how it was happening, but it was. Maybe someone like Ash could throw some light on it.
