Probably parameteres are :

1 ) Engine speed ( more then pre determined value )

2 ) Time on that engine speed

3 ) Another ratio to upshift

if all 3 conditions are OK , ECM will light it :)))) ( I think )

Small triangle with a arrow and a wavy line underneath.

if its a stick shift its probably your upshift indicator when there is little load on the engine it will tell you to shift to the next gear.

I have a 1987 jetta and i want to get my up shift light working again i hoping it is just a blown fuse?

It could be the upshift indicator control unit relay (relay #4, second row of relays, 4th from the right). There is also vacuum switch upshift indicator, (usually connected inline of the vacuum line going to the distributor advance, with an electrical plug connected to it). Or it could be transmission switch/upshift indicator, (located on top of the transmission, towards the back of the transmission). I don't think it would be a fuse, because the upshift control unit relay is powered by ignition battery.
