most obvious mistake with these symptoms is that you swapped the leads for the rearlight. If you connect the phase wire to ground you will have no lights. With B&M lights you will need a torch and reading glasses to find the marks which define which terminal is which. Cycle lights will also connect to ground if bolted to clean metal.

If this doesn't work: as you have a standlight: if the front light has a bad bulb (wrong wattage, or worn) system voltage will be limited and it might take a long time before the rearlight powers on, as it has to charge the capacitor first or something
