How to turn on LED lights with RX plug if i don't have an extra channel?

[chiefroastbeef]

Hi guys,

I bought the GT Power High Powered Headlight system (http://www.gt-rc.com/en/pd.jsp?id=165#_pp=129_780) for my friends WLtoys buggy. However, i realized the WLtoys Rx do not have any extra channels. The headlights have a servo plug in order to turn them on and off. Is there another way to turn the lights on without plugging it into the RX? I tried plugging a 2S battery in, but it doesn't turn the LEDs on.

Thanks!

This light system takes its power from the balance-plug of the battery and an extra channel on the rx provides signal to switch it on-off. It can't be used standalone.

Thank you for your reply, so there's no way i can "spoof" the signal without plugging it into an RX? Thanks again

Welcome to the site!

You can put the LED lights on a JST connector and solder the other side of the JST connector to the battery plug on the ESC.

You can put the LED lights on a JST connector and solder the other side of the JST connector to the battery plug on the ESC.

The controller is taking two inputs, power from the balance plug, and the control signal from the JST.

There are a couple of ways you can do this without having being able to plug in to the RX...

1. You can get a wireless winch remote from Hey-OK or RC4WD, this would give the lighting controller the signal it is looking for to turn on.

2. You can wire around the controller so that the LEDs are on when you turn on the RC. But, you likely will not be able to come directly off of the pack. Most of these LED system that have a built-in controller have 3V LEDs, with a tolerance of ± 0.5v; if you try to connect them to a 7VDC source, they'll flash once and fry.

3. If you do decided to wire around the controller, then ditch the whole system and just go with some Common Sense RC LEDs. They come pre-wired with a load resistor, and they have a wide operating range, 5 -12VDC.

Here the 'solution' to your 'problem:

This doesn't use the Rx, at all. You solder one end to the ESC's battery leads, just as you would an external BEC, and then attach a male connector (JST, JR, or whatever your LEDs use) to the other end. You can't use your Rx for turning the lights on/off, but that's ok...the included remote provides MUCH MORE functionality. Short of replacing the Rx with a higher-channel unit (I'm using a 6-channel Rx, originally intended for airplanes, in my first Capra), this is the next best solution.

Now, get out there, and light up the night.

Thank you everyone for your expertise! I appreciate it, I'll review the options and will see which one fits best for my friend's buggy.

You can plug it into your battery’s balance lead,and then plug battery in. The lights should just come right on. You’ll have to look into other options if you want to have control of turning lights on n off remotely it looks like to me with that light set up since you don’t have a spare channel open

So when I tried plugging in my 2S battery, and the JST plug not plugged into anything, the lights won't turn on at all. I think for now I'll save this light for another project, and just wire up my own LEDs, thanks again guys.
