Red light on speedometer

Thanks troops!
I loved 67Dart's answer. It reminded me of this book idea my friends and I are working on. It's totally made up **** that is presented as fact. Most of them seem possible at first, then you think about it- Hey, Seagulls DO fly on Wednesdays! Dale Earnhardt did NOT collect rare bug specimens.
That kinda thing.
Need a gig, Dart?
I think it is an engine warning light, as it took me a while to even find the high beam switch ( on the floor to the left of the brake)
