Sorry forgot to say always connect LED,S in series not in parallel.
Read this link for a simple explanation about wiring led's ;)Hi Mike most excellent link very easy to understand, even for a dummy like myself. this has been most helpful. cheers to you all. Dan.http://www.theledlight.com/ledcircuits.html (http://www.theledlight.com/ledcircuits.html)

but an led will only work at the exact voltage
I am curious to know why all the posters are using LEDs and not "grain of wheat/rice" bulbs. I know that LEDs have a longer life, but for the length of time that the lights are used on models, is this significent ?
Possibly the current consumption ? But I have 18 GofW bulbs on my latest model and the total consumption is only 1.27 amps - easily handled by the 12v 7amhr battery in conjunction with the 1.66amps(Max) of the motor.
I find that the spread of light is far better than the LEDs which I have on another model which is why I have used them this time.

Thankyou, I have done myself proud with this one, scratch built with no plans, just my imagination!! 8)
Not on a bright sunny day Bryan but I have been in foggy conditions at the entrance to Southampton Water at noon and all the surrounding ships and yachts had their lights on. Also I've noticed that the Channel ferries frequently have their nav lights on during the day even in normal conditions.Read the rules/law...a bit of fun is OK but it should not be assumed that it is normal/usual. Not being a pedant, but a lot of modellers seem to think it is usual to keep the lights on. Wrong.
Personally, on a dull day, I think it's nice to see models with thier lights on and showing up clearly, technically correct or not.

If you run GoW bulbs at lower than their rated voltage they will be less likely to fail. Having said that, I'd make provision for future replacement if you possibly can. Not easy up the mast I know!
at 7.2v not 12v, they will probably outlast the model or you! :)
