[Closed] Another Lights Question - Advice needed

I dont really night ride as i finish work early enough to ride in the light. However last year i discovered 'actual' riding in the dark.

I have a c and b seen light on my bars which seems good and an ayeup on my helmet.

If i bought somthing like a Hope R4 for the bars what is the main diferences between that and my Cand B seen. besides price and build quality.

Thanks for any non sarcastic interesting points.
