The thing I was thinking of making was for the van to make sure it’s lights were working ok

hi Richard, if everything is fine with the car itself indicator-wise then you need to work back from there. check the signals going into the LE box and coming out. Make sure you do it at the actual inputs outputs on the box, not at some other location. Ideally, you would remove the box and see what happens then, that's the easiest way to rule the box in or out as being the problem.
