Hi all

I need help identifying what this bulb is, in the sense of how it is described technically so I can try and cross match to an ordinary bulb replacement, or preferably to an LED replacement.

Stanley 12 v 3.4 sn  the two small locating pins are each at the same level, directly opposite each other.  I don't know what the "sn" means. I need a bunch of them, I want to replace all the bulbs in the instrument cluster of the 82 1200 while I have it all apart to fix some of the wiring.

can anyone help with some info? Thanks!

I haven't tried them, but I found these:

Just do a search for 'ba9s led' and you will get all sorts of different designs pop up.

Paul, go to https://www.superbrightleds.com/cat/ba9s-ba7s/ for a North American source (well, China actually, but that's just reality these days). THe ones I use are most similar to the 3 lumen one, they make the gauge faces visible but are not too bright. I also use the coloured ones in my neutral and flasher lights, and I can see my neutral light in full Florida summer sunlight, try that with an incandescent bulb! They also draw buggar all current, and supposedly will last until the next Big Bang.

Hi Simon and Ken

that is the info I need to search , thanks - ba9s LED, and Ken, great link.

Ken, how many lumens for the bulb, there is a pretty broad range and I have no idea how bright 3 lumens is compared to 13 lumens other than 13 will be brighter? What would the ordinary 3.4 w bulb rate in lumens, I wonder?

I went over to my local Canadian Tire Auto store, they only have the ordinary bulbs, and in 4 watt, not 3.4, last thing I want to do is INCREASE the electrical draw.....

Paul, the 3 lumen bulb is probably about right for the gauge illumination, if you feel you need more it's cheap enough to step up to the 8.5 or 13 lumen ones. Ratings in lumens are pretty arbitrary, dependant on what the manufacturer claims, so it really is a case of try it and see. For the idiot lights I would suggest a higher power one, the 13 lumen one is available in red blue and green so that would be the one I'd try.
Remember these guys just buy whatever the Chinese manufacturers are offering so you probably won't be able to get the same ones next time you buy. But since these things last forever you probably won't ever have to replace them. I've been using them for about 4 years now in all my vehicles and I've never replaced any. I even have some LED headlights, one in my son's scooter has been working very well for over a year now and really throws out some serious light. I just bought a set of H1 LED headlight bulbs that are rated at 4000 lumens, supposedly twice as much light as a halogen H4. Will install them in my car when I replace the crazed plastic headlights, but I need a full day to do that and I never get that much time to myself these days.

Hi Ken

thanks again for the link to the Superbright site, I think....... ;) my vehicles will thank you, my wallet, not so much  ;) ;) ;) ;)

according to PayPal my weak, weak Canadian dollar is worth a whopping 0.79 USD. Ouch.....

however, couldn't find the products that are on the US Superbright site here in Canada anywhere even after a lot of searching, so went ahead ordering from the good old U.S.A. I ordered 40 of various colours and beam angles and lumen outputs (3, 7, and 13) of the BA9 LED's to try out in the various motorcycles as well as the Spitfire car, which also uses those bulbs in its dash.

I also ordered a couple of sets of LED headlights to try out, according to the reviews they are TWICE as much light output as the best Halogens. I just spent $80 locally on the highest output brightest possible Halogen bulbs for the Triumph Spitfire, so $99 USD for a LED set that supposedly puts out twice that much light seems very reasonable, I am going to stick a set of the LED headlight bulbs in the Spitfire, combined with the very loud exhaust maybe that will give the wee tiny car a fighting chance of being noticed in traffic. I am also going to try out the LED headlight bulbs in the various Laverda's.

At least you are a wopping 3c in the dollar better than us here in Aussie.
Say B9as are readily available here in Aus and if you need a LED version you can even choose the colour.
Though I tried a numerous of these in the RGS park light but gave us as they only seem to last a few months at best.
Back to normal globes for me and not sure why you would want super bright globes in your instruments unless for the indicator one I guess .....( I seem to have a habit of leaving the damn things on when on the 3c... the modern bike ( RGS ) doesnt seem to have the same issue.. perhaps due to it self cancelling..

I reck one you are gunna beat me with you project they both have been running for about the same time frame... I am more optomistic and have set a deadline of June 22 as that is club rego day.

Well that is my 3cents worth...

 
Hi Brett

I ordered a bunch of different LED's to try in cars and bikes, as well as a couple of sets of LED headlights that are supposed to be twice as bright as Halogen's. As ridiculous as it sounds, I have 8 cars at the moment as well as 8 bikes, so the LED's will find a use somewhere. For the small LED's I ordered 3 lumens, 7 lumens, and 13 lumens, in 6 different colours, and in 32 degree and 90 degree beam patterns. I figure the general dash/instrument lighting should be the wider beam pattern and the lower lumens, and the various indicator/idiot lights should be narrower focus and brighter. In theory anyways, we'll see how they actually work out, when they get here from the U.S. I am not delaying the progress of this build waiting on LED bulbs, late to day I found some 3.4 w conventional bulbs that fit, cost me $25 for 10 new conventional bulbs which I have now already installed in the instrument panel/gauges/idiot lights, and I will install the instruments tomorrow and continue forging ahead. Easy enough to go back and stuff LED's in later.

my previous experience with LED's on a Laverda did not turn out well, but that was several years ago. The first time I fired up the 71 SFC 750 8000 series drum brake it blew a taillight bulb. 7 or 8 tail light bulbs later I thought I would try an LED 1157. The SFC turned the LED bulb to powder the first ride....... I finally bought a heavy duty Harley Davidson 1157 bulb which has extra supports for the bulb filaments, those seemed to last at least a couple of rides.....

I am hoping to fire the 1200 TS Mirage of the first time by next weekend if not sooner, I am just waiting on some ignition bits from Red, wow, incredible service and support and follow up from Red, I am hugely impressed! By email and exchanges of photos and details, Red figured out what my electrical and ignition issues were, figured out how to solve them, then fabricated the required bits more or less instantly. Highly, highly recommended.

I have paid for quick shipping from AUS so the final bits should be here in the next couple of days. I have been throwing a ton of time at this build in the last little while, another 10 hours today, maybe at least another 5 or 6 hours tomorrow, amazing how quickly the pace picks up when you commit to spending some time on the project each and every day for a couple of weeks. ;) 8) Also amazing how setting a public deadline for yourself can provide motivation, at least for me! However, also amazing how much of a time suck getting assembly just right actually is, tweaking and adjusting as I go, in addition to having forgotten how some of this stuff goes back together after leaving it in pieces for two years...... :o :o

Greetings Paul,-
Have you made any discoveries as yet with your LED replacement experiments? 'Especially interested in your H4 headlamp and 1157 bulb findings...
-Galen
 
I have tested these LED bulbs and compared these with the original lights. The LEDS have a narrow beam and don't spread the light through the gauges. So the final light effect is much less.

These bulbs are perfect replacements, same size, same Watts:

And here is proof. LH clock with the above LEDs, RH with the standard incandescents. I ordered a pair to try them out and they arrived this afternoon
(Trip meter has a non standard special led I made up)

Don't understand that. I've put LED's in my instruments and they are far brighter than the incandescent original lamps. Stuart

Are they the same ones as described above? If so, I agree, it's a bit strange.If not, it would be interesting to know exactly what they are.
 
I just arrived back in Calgary, Alberta, Canada where there are real internet connections, after 9 days on Vancouver Island in nature's paradise on the ocean......

as I noted previously

For the small LED's I ordered 3 lumens, 7 lumens, and 13 lumens, in 6 different colours, and in 32 degree and 90 degree beam patterns. I figure the general dash/instrument lighting should be the wider beam pattern and the lower lumens, and the various indicator/idiot lights should be narrower focus and brighter. In theory anyways, we'll see how they actually work out,

All the bulbs are here. While I was away my son installed a set of the LED H4 headlight bulbs in the Triumph Spitfire car, the things are so bright I am wondering about attracting unwanted police attention. Scorchingly bright, way way brighter than the very best H4 halogen bulbs I have had in there.

I will install the various small LED configurations later this week, and report back. Ppuuxley, what bean angle and lumens are the LED bulbs you show in your comparison photo?

On an allied subject- the rubber lamp holders on mine are so age-hardened that they are extremely difficult to get out the back of the clocks to such an extent that there's a real risk of tearing them in doing so
Anyone got any tips for removal or a source for replacements? Not keen on slavering them with too much lubricant in case if finds its way onto the dial faces.
 
I had my clocks refurbished by CB750 faces, top job and he put new rubber 'boots' on where reqd. I got my instrument LED's from Paul Goff (UK) and they are definitely brighter. Having said that the old ones were so dim anything would be an improvement. I wrote earlier that the tail/stop LED was nowhere near as bright as an incandescent jobby so it's back on the shelf.  Stuart
