PRAVX II S

Nice, PRAVX!

There's some very detailed info there on how it works, and how to install and even build the circuit.

But how does a driver operate it?

I assume that, when the ignition is OFF, the circuit has no effect.

In the particular case of the VX donor vehicle, when the ignitiion is ON, what setting does the lamp stalk/dial need to be on in order for the photoelectric circuit to work?

( a ) It can be set to OFF, and the lights will automatically turn on as long as it's dark and the ignition is ON. (That means that, in order to force the lights off, you need to install and close the optional override switch.)

( b ) The switch must be set to either the park light or headlamp setting.

( c ) The headlamp setting must be set to ON. (In this way, the headlamp ON setting on the dashboard or steering column would work much like the headlamp AUTO setting on IS250's. The downside is that you cannot force the lights ON during a bright day.)

Hey mate thanks for the positive comments.

To answer your question there is a override switch (master switch). So if i dont want the auto headlight module to be active i just turn it off. the switch supplies Ignition.

If the module is in active mode or not in active mode in the day i still can use my lights by using the OEM switch.

At night if i want to turn my lights off while driving or IGN is on i will have to turn the master switch off.

Hope this helps mate.

Update.

I have uploaded a video. The clip will show the actual auto headlight module operation on the car.

The donor is a vx commodore.

Hey guys my mate wanted his lights to turn on when it gets dark with out him touching the switch.

So i made him a automatic headlight circuit.
