I think I have this correct after pondering and finding the correct parts in Canada in our weak dollar. ST1300 2006.

Clear lens...found
LED electronic 2 pin flasher...found
LED switchback bulb...well here is the question.

And yes, I have searched and read the forums but want to be certain.

Instead of changing the receptacle for the new LED switchback bulb, could we not use the existing holder and use a bulb that fits? I see where we change to the old twist and lock 1157 receiver, but why not use a bulb like the
3157? I am not sure if the 3157 will fit in the stock holder.

Any help with this? If not I can change them to the old style easy enough.

Bulb numbers please, and hopefully on the north side of that imaginary line so I can remain frugal.

I don't believe I'm familiar with the Canadian ST1300 but ours use the 7443 bulb.

Does Canada use a two-wire or three-wire socket? A three-wire socket is needed for the running light/turn signal functionality and the factory socket provides that on our bikes.

So a switchback bulb (7443 base) is plug n play.

I used these— 60 white/60 amber LEDs.

I believe the 3157 base bulbs are used on the 1100 here.

Thanks, the Canadian model is the same as the US model except for the speedo and other unknowns to me. Yes the holder has 3 wires in so the 7443 base looks like it. Thanks.
Another question, do you think they add to seeing the roadside or ditch or is this just about being seen?

I used those because they worked and others I tried did not. Other members will have cheaper recommendations that also work but I didn't know about them when I got my bulbs.

3157 and 7443 look very similar, both are 3 wire, but they are different sizes. 7443 is the North American ST1300.

This mod is about being seen. No useable amount of lighf going forward, unless your speed is all about walking. I do see the white light in front of me... but under 2 meters of useable illumination.

Thanks for the correction. I was confusing the 3157 as some version of the 1157. Different bulbs same function.

It is. The 3156 and 3157 are the same basic bulb as the 1156 and 1157, 2 filament and 3, respectively. Dropped the bayonet base for the less metal no solder push in connection.

Here are the three pieces that I am about to order. What do you experts think about this?

Expensive bulbs... I'm a cheap-o, $20 is the most I pay.
I would ask if they are white off when amber on. Some bulbs suppress the white and keep it off when the amber is in flashing mode. This is much more visible then the models that turn the white on between amber flashes. Somehow they are known as type 1 or 2... but I can't remember what one it is.

Good point though I will mention that when this first started way back when there was no mention of Type 1 or 2 that I recall and I made no inquiry. In trying three different sets of switchbacks I never got the 'wrong' type.

I don't know if those are the same as my bulbs but I like the 60/60 count.

A hint about the clear lenses— it's my feeling they all come from one or two manufacturers at the most just different vendors. You'll need to take a small file or knife to clean up the flashing from the mounting holes so the sockets fit cleanly. Just takes a few minutes tops for each lens.

IIRC that flasher tab should be cut flush with the top of the case and it will fit in the rubber holder perfectly replacing the factory flasher. I don't remember what the connector looked like.

Well the bulbs were the last items to come in for this transformation. I am not sure about the bulbs, so may order other ones but for now they work, just more blue than expected, especially next to the other LEDS. The bulbs are also very long and barely fit in the clear lens. Here are some photos...

I had tried the stock flasher but nope, so I plugged in the electronic flasher and it made the signal light flashes normal. Now to look for some whiter LED switchback bulbs, I will have to see, 5000 is more white than 6000?

Yes 5000K is whiter than 6000k. Sunlight is said to be around 3500K depending on the source of info. Halogens look very yellow.

There are different variable that can account for perceived color but those lights of yours look more like 7K which takes you into very blue territory.

The Evitek G6 headlights are rated at 6500K while the F2s are said to be 6000K. I don't know how accurate some of these vendor/manufacturers' ratings are.

That's Kº.

I just received my new bulbs. These are the ticket folks. Bright and white...and yellow.

See the white from blue and the yellow is so much brighter.

Might want to give these a burn-in, literally. I had a set of similar design (actually 2 sets, one set is now my tail signals since I don't need white). After a month or two the white burned out. My guess is overheating in the small confines of the space and being in the sun.

I'd recommend you put them in the oven and set it to low (120° F), hook up a battery and see if they live for an hour or two. I'd figure 120° is what they would see sitting all day in the sun.

If they live.. send me a link so I can buy some too. :)

Made me think of something without torturing the bulb...I am thinking drill a small hole or 5 across the top and a few at the bottom of clear lens under the mirror cover. I don't believe that much rain gets in there as I look inside, but maybe that could help bleed off some heat in the small space. Just thinking...:think1:

What are the specs of these new bulbs?

A lower color temp is not 'whiter' but less blue and the colors shift toward the red end of the spectrum. 2700 K is called soft white and is closer to incandescent. It will look yellow when compared to a 6000 K LED.

A few words about LEDs - and this comes from a lecture two years ago by a research scientist (nearly pre history as far as development of electronics and LED's are concerned). The color temp of a given sample of a manufacturer's LED's can change, either going up in temp, going down in temp, or even going up and down. The amount of change and when in the lamp's life the change happens is not predictable, though I've been told the new lamps are more stable than those from a couple of years ago. As said, heat kills LED's, and I would not play with the oven to 'test' your lamps. Why bother? It's not a big deal to change them should they burn out. It is my opinion that drilling a few small holes is not going to give you significant air flow to cool the LED's, but I would bow to someone like Spiderman here. LED lamps lose brightness by 1 or 2% a year, but these numbers are for a nearly continuous burn. For most of us, an LED lamp is a lifetime investment because very few people leave their lights on for 8 hours a day, 5 or 6 days a week....and therefore we will never be able to perceive the loss in brighness.

Very nice! The matched color look much better than that purple haze.
