I'll take another few photos. The lights are called B Seen 101 and I got them on eBay from a reseller who I believe sources liquidated goods. Further investigation reveals the company behind them no longer exists. They used to charge a ludicrous £90 ($180) for them, no wonder! I got mine for £7 on eBay UK and £9.50 delivery in the UK. That covers multiple purchases up to 25KG so I bought 4; one for another bike and the rest to keep as spares. Here is the listing:

Sadly they do not send outside the UK but you could always get a friend to get them for you if you really desired the unit. I find them excellent and it really increases my visibility in London, night and day.
