Those lights definitely put out lots of heat. I'm always deathly afraid of starting a fire when I use them.

A flat adhesive-backed fish tank heater might do the job if it stays stuck. Thinking along those lines, I figured there must be stronger heaters of the same design for RV waste tanks, and sure enough there are:

Unfortunately, they're $100 which puts them far, far out of "pays for itself" range. It might make more sense to retrofit a block heater into the transmission.
I'm not sure I agree that it makes sense to heat the gear oil in a manual transmission, though. I don't think it takes long to get to operating temperature. It's unaffected by whether the engine is on or off. If you really wanted to deal with it as a problem, you could use a premium synthetic multi-weight gear oil.

Again, it won't pay for itself...
