Hood glowing red hot

[davepl]

A good solid 35 years ago when these trucks were current and I was a little kid, my grandpa borrowed my Dad's 68 GMC 910 to drive down to North Dakota from Saskatchewan to pick up something or another.

About 8PM that night we get a call from grandpa who is pretty worked up that the engine is so hot that the HOOD is glowing RED HOT.

After some back and forth debugging and troubleshooting, it was determined that Grandpa had never driven a truck with roof lights before!

Apparently just around dusk the glow from the roof lights casts onto the hood with their orange bulbs and makes it looks like it's "glowing".

Almost forgot about that one! Haven't driven my truck at night yet, actually...
