How did they get the trailer lights to work w/o being hooked up? Has to be Wireless but with what? Kit or custom? Last edited by Kausekaos; 12-10-2013 at 09:12 PM. |

As it says in the video description
"RC-truck Tamiya Scania with Leimbach roll-off kipper and trailer. Trailer is selfmade with brakes and wireless lighting system. Servonaut speed controller and soundmodul." I don't know if this is the same one in the video, but it is one example. http://www.ss-tronix.co.uk/tamiya-wireless-trailer/

There are a few different wireless options for trailers

Re: Trailer lights working w/o being hooked to truck. How?
SS Tronix uses a infra red sensor through the 5th wheel pin and once truck is unhooked , the lights on trailer will stay on but cannot receive new commands until hooked back up. I noticed in the video the trailer back up lights came on with truck detached.
Must be a system based on radio frequencies?? Mario |

Re: Trailer lights working w/o being hooked to truck. How?
I use the SS-tronix system on all my trailers - the system does have a test feature which turns on all the lights on the trailer, until it receives a command from the I/R LED on the truck. Whilst I haven't tested other scenarios, I imagine its possible that if the trailer lights are turned on and you remove the I/R signal, then the receiver unit in the trailer may hold the most recent command until a new signal is received...ie. lights stay on when the truck is disconnected.
I have added a switch to the support legs so that when the legs are down (ie. trailer disconnected), power to the receiver unit in the trailer is turned off so all the lights go off too. the unit powers up again when the legs are raised, which only happens when there is a valid signal from the truck LED. Added bonus is it saves trailer battery life.... |
