Do not fear we will have a new light in the post next week, and will take a look at yours (will check warranty process). As there was no issue with the connections (from what you said) and from what you have told us the fault appears to be with front light. A bad connection is the most likely problem but does not appear to be the case for you.
Also note B&M lights with halogen bulbs are replaceable however yours has LED lights. I will be speaking to B&M next week, was hoping FLI distribution would provide a named contact but does not appear to be forthcoming. The halogen version is held in by a clip at the front from memory.
