We all know Optima is the only battery to have in our trucks. The quesiton is, which color top belongs in a Cummins engine bay?

I have twin D31T Optima Yellows (the largest they make) on my Toyota Land Cruiser with a 4. 2 Hino tubodiesel. I acedentaly left the headlights on for 4 hours. When I finally discovered my goof, the lights were still on and it started right up:-laf. After my OEM dies on my CTD, it will be replaced by either a D31A or D31T Optima Yellows.
