Not sure of the best place to put this so Electrical gets it

The instrument panel that I have has warning lights for the brake fluid, antifreeze,and windscreen washer fluid reservoirs but the reservoirs I have don't have a switch in them.

So the search was on.
They come in vertical or horizontal mount.
The ones I got are vertical mount. The also come in normally open(NO) and normally closed(NC) configuration.
