Hopefully it's just because the brake fluid in the reservoir drops as the discs & pads get lower as more fluid is in the brake pistons. Just top it up a little bit - if you put too much in, when you come to change your discs & pads (soon if you're getting this light) it will overflow.
I absolutely agree, reckon that's spot on advice. When the light shows the level has dropped to that extent, I think it's a good idea to take the wheels off and actually inspect the pads front and rear, as there's a good chance they'll be down to the last couple of millimetres. The separate pad wear indicator light shouldn't be relied on as the wiring is fragile and the rear pads aren't fitted with wear indicator wires. Much better to catch them before it's metal-on-metal and a ruined disc...
As for using old fluid, if kept in an airtight container it should be OK. Brake fluid in the system does absorb moisture and should ideally be changed every two years (it's cheap, after all, and cheap insurance against corrosion problems). When I change pads I undo the bleed nipple before pushing the piston back (or pushing/rotating the rears), which squeezes out most of the old fluid, and then I top up the reservoir with fresh fluid. A quick bleed to finish off and it's effectively changed. If not confident then better not to attempt to bleed the brakes yourself, won't cost much to pay someone for this relatively quick task and ensure more problems aren't introduced by accidentally letting air into the system.
