One wire control for up and down. Rev 1.8- Negative side switched

Track (one wirer control for up/down solanord's ) Negative side Switched 
The lights on the circuit are Blue and light Blue, you can choose which side is up or down. 

Note: The two lights are acting as solanords and the fets are able to handle around 15 amp i think. 
The info state pulsing gate not constantly on.  Please do not take the info as currect i'm still loaning  about Fets.

I have traced the one wirer (Colour blue)
IRF540N Fet Transisor  Note: Fets on this app are reversed i'm not sure why this is. 

I'm  not sure way the N-channel  fet arrow point out not in .
The Fet might be a N--channel but the circuit shows me a P-channel fet. (Picture only)

I have fix the Fet info up to mach the circuit.

Nice schematic now.....good job done...your description needs altering to match this good circuit...if it was a pfet as described, then there would need to be a re-think. (and just alter the LED resistors to keep them just below 20mA for each LED).

Thanks again 2ctiby. I have a problem with spelling, so I'm happy to take input.

You are welcome. Your last sentence says that the fet is really a p- channel. If that is the case then the circuit that we see here would need some alterations because they are considerably different to n-channel fets.

The info that i keep looking at shows pictures of fet that point in reverse direction. This is way I'm saying that.

I just did a search for a N-channel fet and all the arrows point in not out. This is way I'm stating this..

I know what you are saying and I agree that it can be quite confusing, but this might help.... https://www.google.co.uk/search?q=N+channel+fet&newwindow=1&prmd=isvn&tbm=isch&tbo=u&source=univ&fir=cRfum24l9NwEdM%253A%252CrU16tbq1CyZnaM%252C_%253BXkJ6t2yxYYgozM%253A%252CobmyDYv1p6g-6M%252C_%253BQoJW22wr5Jyd7M%253A%252CjYL4cRcFsvDRBM%252C_%253BJxNDwRdSXI8uDM%253A%252C_CtQAEfEieBjDM%252C_%253BPwBxu73BJ8TVvM%253A%252Ck22dIa4LqAoJTM%252C_%253BWWy5TFbV-ZhObM%253A%252Ck22dIa4LqAoJTM%252C_%253BWaR4XW7qoT3vLM%253A%252CsfVCXu2y1IbLnM%252C_%253Bl9-rhersnnVJwM%253A%252ClP77EQyFV7A12M%252C_%253BiFo-RHuxjItAJM%253A%252Cqryai6MIRczX8M%252C_%253BZ9UgOmXkyYzqhM%253A%252CBmV5ZjdC4fOosM%252C_&usg=__LrybBAgG14fY69gB1xKy6Hx9bW4%3D&sa=X&ved=0ahUKEwispfvIqtLQAhUFM8AKHXW5D-kQ420Iew&biw=1024&bih=768&dpr=2#imgrc=ErhLHOsq5jhVtM%3A
