I added another rare optional extra to my collection today. It's called a 'conlight'. At first I had no idea what it was and had only ever seen a tiny thumbnail of one in the original sales brochure. There is absolutely no information or pictures of them anywhere online so I wasn't sure if it was a light, a sensor, a strobe light for some quirky Japanese outdoor dancing, or what the heck it was, but after looking at it a little longer I figured out that it's an automatic headlight sensor!!
The clear lens faces towards the front windscreen and detects the level of light outside. As soon as the sun sets and the light level is low enough (or you go under a bridge etc) the park lights and/or headlights will come on, depending how dark it is. The headlight stalk is always set to off as the sensor does all of the work (however you can switch the unit off or select that you only want the park lights to illuminate so you have manual control over when the actual headlights come on).
It was 100% plug-and-play by using a special loom that it had specifically for this option. All I had to do was unplug my existing combination switch plugs and connect them to the new connectors, which basically just acts as an extension with wires branching off it for the conlight to function.
The beauty of this option is that you can never accidentally leave your headlights on as the unit only works when the key is turned to the 'ON' position. It's pretty gimmicky but would have been very revolutionary in it's time. A lot of the newer cars these days don't even have such a feature as it seems to only be limited to up-market and 'luxury' cars.
I personally think it's a great quirky piece of Japanese ingenuity and it's another thing to add to my growing list of optional extras
