Dash lights flash bright just before stop
 

I've had this going on since I bought the van and haven't seen any probs with it but I'm curious none the less.

When it's cold, as I'm going slow down my street, I slow down and stop at a stop sign. Just before I stop, all the led's on the dash - odometer, thermometer & radio display flash really bright for about a half second. It's almost like rolling the dash light dimmer up to the spot that is full brightness - just before the dome lights come on. It seems like it does it when the trans downshifts but can't be sure of that.

Just looking for a little info if anyone has run into this before.

Thank you in advance,
Joe
