Hi guys was hoping to get a little help setting up DIY sleepy eyes on the 180.

Someone put me onto cutting one of the wires on the back of the headlight up/down button on the dash. Now the headlights will stay up after they are turned of, until you press the button in which case they go down. The difference is that if you unpress the button while they are going down they will stay at that point.

What I waned do do was hook up a little timer relay so that when the headlights are turned off on the stalk, it lets current flow through the circuit for a set amount of time, which is set by a trim pot. THerefore you can set it up so that the headlights will automatically go down to a sleepy eye position everytime, doing the job of a $200 jap headlight controller.

Would something like the Jaycar kit below be suitable to do it

Am I on the right track or am I a crazy mofo?

yes, that'll do it, and yes you're a crazy mofo

theres actually kits designed to do this. knowing jap brands though it may cost an arm and a leg

Did you ever end up doing this? I want to make my gazelle sleepy for less than $200 or whatever pivot charge you....

gazelle headlights do some funny stuff. They have switches that sense if it's not 100% up or down, and power up the motors.

That's why you can't do the manual wind up trick on them either.

It should still be possible to do it electically, but you'll probably have to disconnect all power to the motor system.

Ya i just checked it all in my manual, as far as i can tell only aussie s12s are like that, overseas ones are the same as s13 , upside is that i reckon i can use an extra on/off on the up/down switch to park them where u like (you can do it by balancing the up/down switch at the point where it doens't contact either side to stop the lights to). Back to the s13 I've seen on a Drift Tengoku video where a guy with a s13 just adds some switches to the main relay to make the lights stop where he wants to. I can prolly find that and make a diagram if ppl want it.

In one of the Option DVDz i think its 14
it shows u how 2 do the sleepy headlight thing
all you needed was switches and wires which are going to b connect to the fuse box

Even tho it was in Japanese u can still get the jiss of it coz he shows u a diagram

I haven't tried it tho
Coz i've got a Silvia

if i have time and if u guys want i mite encode that part for ya but i dunno where to upload it coz it mite be a big file

I totally forgot about this project. I ended up buying the jaycar kit and its sitting in the draw next to me.

The advantage with mine and the Pivot one is that they memorise the headlight position each time where as the others you have to set up it everytime you turn the headlightts off (i think).

hahah ....my friend bought a set (pivot) from the net for $140

I think they work slightly different to the Jaycar kit.....instead on work on a timer system....the Pivot kit actally works with some kinds of resistors to alter the amount of voltz/current (not sure of technical term) going to the motors.

The pivot kit does go back to the position where you have set it to too.
But for some reason, he doesnt like using it....as the light will go down first before it goes up to the full open position....just like if you have done it manually. he thinks it might do something to the motor......

you guys reckon it would??? I am interested too.

ya i've seen that option video, its pretty simple so maybe all that's needed is a quick diagram and some instructions.

If you search on nissansilvia.com someone posted up the diagram for the option one I think...

I have this hooked up on my car just like in the option video and it is EXTREMELY easy to hook up.

l6a6w6s6, There are two switches, one controls the power to the motor - height (on/off, when you turn it on, the light comes up, when you want it to stop you turn it off, MUST BE QUICK) and the other disables the motor from lifting or closing the light altogether so you can turn the lights on and off with the pop up headlight stuck in the place chosen by the first switch.

I have the diagram if it's not on nissansilvia.com.

The only advantage your setup will have is that you don't have to manually adjust the height with the switch, but once it's set, it's set with both methods. Sounds like a good project anyway and I'd like to see the results.

BTW. You do realise you cannot see with the headlights halfway up at night. It is only for daytime. (Unless you adjust the bulbs upwards)

I'm a little confused....

The way I want mine to work is as follows.

1. turn headlights on and they come up the whole way and lights come on. still functional at night.

2. turn off headlights and they only travel a partial amount down to the sleepy position. Therefore the height is memorised.

3. Repeat

I know the wire to hook up the relay to, its one of the ones that goes to the headlight up/down button in the cabin (not the actual headlight stalk). I plan to only allow the current that sends the light down to run for a set amount of time, and will do this via the timing relay. So once the relay is triggered by the headlight stalk being turned of, the motor is allowed to run for a set amount of time controlled by a trimpot on the relay.

Therefore increasing this time makes the headlights be more closed and decreasing this time makes the headlights stay more open.

Simple in theory hard to explain, but I'll get onto in the next few weeks for sure.

If you get a wiring diagram for the pop up lights there should be switch for the down postion if you moved the switch or replaced it with a new limit switch to send the signal its down when its only half way it should work

Dumhed might be able to help or explain this better than i can

yeah if you really want sleepy lights all the time you could probably either move the limit switch, or wire another one in and mount it on a bracket somewhere on the light assembly
