You could wire direct to the battery as this built in protection is there to protect you from flattening the battery, however i do recommend the brake light switch with inline fuse
Do test it first though, I had a pair that drained the battery to 5v without cutting out.
Also, I had a (different) set with the Oxford digital gauge that started doing what you describe - not coming on with engine at tick-over. They didn't always do it, but started doing it then did it for about a week, then stopped turning on/off. The digital gauge was at fault, Oxford replaced it for free even though it was out of warranty

Might be worth putting another gauge in there if you've got access to one, see if that is the problem.
