mine dosnt do that either it stays at a steady even flow of electricity and dosnt fade or anything and have any of you noticed your tire pressure indicator light up during the cold parts of the winter

The tire pressure indicator lighting up is normal, as it gets cold, the tire pressure will drop. once you drive at high speeds for a while, they should come up. My Jeep GC has the read out tire pressure moniter, with the actiual numbers, in the summer they read like 31-32 now that its been cold, they read 26-28..
