Turn signal switch wiring

[Pizzabroodje]

Hi!


I want to install this head- and taillight on my ebike with a BBSHD and shark battery:

The rear light has turn signals and a brake light besides the normal rear light, and the headlight also has a horn.
The headlight came with a two button switch, one for the horn and one for the light. The rear light however didn't come with a switch, and as it turns out they don't even sell a switch for it.
I found switches like these:

https://aliexpress.com/item/Universele-Motorfiets-ATV-Bike-Scooter-7-8-Schakelaar-Claxon-Turn-Signalen-Op-Off-Light-12-v/32578477428.html

The problem is that I don't know which one would work and which wire to connect where.

The power will be provided by splitting the power output of the battery with a parallel Anderson splitter, and I have Andersons with pigtails to connect to the other ends.
I would solder the wires of the switch that need to be connected to the head- or taillight together with the other corresponding wire.

The wiring is as follows according to the seller of the head- and taillight:
Rear light:
Black Cable Rear Light "-" Main Connection
White Cable Brake Light "-"
Blue Cable Brake Light "+"
Red Cable Night Vision Light "+"
Yello Cable Turn Left Light "+"
Green Cable Turn Right Light "+"

Headlight:
Green Cable Light "+"
Red Cable Horn "+"
Black Cable Battery "-"


Could someone figure out what switch would work (preferably one of the first two) and make me a wiring diagram of how to connect everything?
I don't want to use the brake lights (as it's either brake lights or regular rear light).


Thanks in advance!

and how to wire them.


There is also his main build thread with a post on them:

Thanks for your response.
However, the threads you mentioned are about how to built it with separate lights. I already bought the lights mentioned in my first post, which have the turn signals etc. build in and I'm looking for a solution to make those functions work with one of the switches mentioned above.

Hi!
I found switches like this one:
https://aliexpress.com/item/E-Bike-3-in-1-Front-Light-Hoorn-Turn-Licht-Schakelaar-Elektrische-Fiets-Schakelaar-Elektrische-Fiets/32921562807.html

The wiring is as follows according to the seller of the head- and taillight:
Rear light:
Black Cable Rear Light "-" Shark Battery Negative
White Cable Brake Light "-" Shark Battery Negative
Blue Cable Brake Light "+" Switched Shark Battery Positive - main on/off
Red Cable Night Vision Light "+" Switched Shark Battery Positive - main on/off
Yellow Cable Turn Left Light "+" The green cable for left turning light switch.
Green Cable Turn Right Light "+"The blue cable for right turning light switch.

Headlight:
Green Cable Light "+"The grey cable for switch of auto light 2.
Red Cable Horn "+" The brown cable for electrode 2 of horn.
Black Cable Battery "-"Shark Battery Negative

I don't want to use the brake lights (as it's either brake lights or regular rear light).
I would still wire it up to turn on and off with the bike anyways just for extra visibility.
Thanks in advance!

If using the first switch you listed: https://ae01.alicdn.com/kf/HTB1yQ4rXffsK1RjSszbq6AqBXXam.jpg

The white cable for switch of auto light 1. = Switched Shark Battery Positive

The grey cable for switch of auto light 2. = Green Cable Light "+"

The yellow cable for electrode 1 of horn. = Switched Shark Battery Positive

The brown cable for electrode 2 of horn. = Red Cable Horn "+"

The red cable for turning light power input. = Switched Shark Battery Positive

The blue cable for right turning light switch. = Green Cable Turn Right Light "+"

The green cable for left turning light switch. = Yellow Cable Turn Left Light "+"

What do you mean with 'switched' shark battery positive?
Also, is this using only the switch mentioned above or also the one delivered with the front light? (I only want to use the one mentioned above, to turn the headlight, rear light and turn signals on/off and to control the horn)

I indeed want to connect the the on and off to the rear visibility light as well, but you can also connect the brake handles to the same light, which I don't necessarily want as I will only be using it for visibility and not as a brake light.

Ah, well, I don't know the answers to that. Sorry I couldn't help.

What do you mean with 'switched' shark battery positive?

I mean your ignition wire or on/off key switch. You don't want this wired to 'constant' voltage or you could drain the battery if you forget to turn these lights off.

If your battery has its own on/off switch or key and the bike turns on 100% without some other power on/off push button, then wire to battery positive. The lights will work only when you "turn on the battery".

If the controller needs a key or switch to turn on/off, then wire to that 'switched' or on wire. This way it only works when the battery is on if it has a switch AND the controller or ebike is turned on. Even if the light is left on or a turn signal is still flashing when you turn off the bike they won't draw power or work again until the bike is turned on again. This way is much better.

Also, is this using only the switch mentioned above or also the one delivered with the front light?

My assumption was the 2 button switch that came with the headlight was to be replaced with other one that has lights/horn/signals

For each side you need a time activated relay 2 or 3 pronged, depending on your switching voltage another regular 3 pronged relay, and a single 3 position switch.

I don't think it's necessary to have the lights go out together with the bike. The battery is 52v 17.5ah so more than 910Wh. That would take 60 hours to drain from 100% to 0% if the combined wattage of the lights is 15w.
Also, I don't know where exactly I would have to connect it. (I have a BBSHD with DPC-18 display, and the shark battery has an on/off switch, but I don't want to take apart the battery)
I think it would work by first turning the battery on, and then the button attached to the display. I will probably always leave the battery turned on, and turn the E-Bike on/off with the button of the display.
I'd also rather not touch the cables of the display remote, as it would cost €80 to replace.

For each side you need a time activated relay 2 or 3 pronged, depending on your switching voltage another regular 3 pronged relay, and a single 3 position switch.

I don't know what this would be used for. And what you mean exactly.

I was on phone so I couldn't write a lot.

You have 2 separate problems.
1, The switches in these are not meant to switch actual loads, they are meant to switch signals. The same way your battery has a max volt and amp rating, a switch has a max volt and amp rating. Of these chinese switches, it could be anything. You can cook/short them if you pass through a lot a power.
To solve this you need relays. They work similar to a transistor. You give a strong input (battery or inverter power) hook the output up to the light, and use the switch as a signal, it will let the power through when the switch sends the signal (usually above ~2.5v is on, under it is off).

2, You want the turn signals to blink, right? You will need a timed relay to do that.
You can even find adjustable ones.
https://www.ebay.com/itm/2-Pin-12V-Electronic-LED-Flasher-Relay-Fix-Turn-Signal-Bulbs-Hyper-Flash-Issue-/153282229941

So in short. If you are running a few leds that are barely visible during the day, you might not need to bother. If you will have 20 led indicators and 80 led brake lights like me, you need the relays. If you are fine with your indicators not blinking (they won't by default) you can ignore the second one too.

I asked some switch sellers, including electricscooterparts.com who seem to be legit, and they say the switches can handle 52V at about 1A.
This is more than enough as the headlight uses either 12W or 4W (according to AliExpress 12W, according to eBay and Amazon 4W), and the rear light most likely doesn't use more than 6W. This all would come to a maximum of 0,34A at 52V.
Instead of a relay, I could also use a 52V DC to 12V DC converter right? As the switch would definitely work at 12V (that's what the AliExpress seller's rate (most of) them at).

The indicators WILL blink by default, as that function is build in to the rear light.


This is what I'm trying to do (same head- and taillight). This switch is still in development by the seller of the head- and taillight though. It would have been on sale some time ago but that got delayed for some reason:

That's cool. I used regular universal motorbike parts so they don't have it integrated.

Well the lights say 48 to 60v, so it should be fine running off pack voltage if that's what you are after. If you use dc converter the lights might not turn on. At this point, I would risk it use the switches at 52v(especially if they said so) but get a 2A fuse that can handle dc 48v in line with all the lighting electronics from the battery.

There is nothing special done in that video, everything and more can be done with the switches you bought, after you get the previous part figured out.

As to the fuse, I already purchased an inline fuse holder and some 2 amp and 3 amp fuses. I will use the 2 amp ones to begin with per your recommendation.
I also bought the first switch I listed as you and 2WheelsMovesTheSoul both say it will work.

Yes.

I soldered everything together today and everything works as supposed to!
Thank you very much for your help!
