They aren’t brilliant are they.the built on lights of my December 2008 purchased proconnect are very poor, infact it would be better if I just lit candles and threw them ahead ! Added some bycygnals in the end - a bit rattlely but do the job.
I know 50 Cycles have found a way of fitting a BM LED rear light to the older Pro Connects so I might buy one off them. The front light is more of a problem so I believe. It all comes down to the way in which the 6 volts is delivered to the lights. Or more precisely, how the voltage is reduced from 24 to 6 volts.
This is something that I intend to look into before winter arrives. I would like to achieve a nice powerful front light. Something like the B+M Lumotec IQ Cyo on the front, which according to their data sheet can be run from a 7.2 volt battery supply, and reliable LED rear light. Both switched from the handlebars as they are at present.
