If trains on the national network need yellow front panels why
doesn't the same apply to LUL?

It has been suggested previously it is because LU do not normally
allow maintenance staff access to the live railway.

You may have noticed LU's battery maintenance locos do have yellow
panels...

Talking of which, I came across this YouTube video of an unusual rail
tour, with LU battery locos topping and tailing Mk2 Gatwick Express
