Ive got a primary/secondary E6 schmidt halogen pair,
its the kit a lot of overnight Paris-Brest-Paris riders use
will sell it, never used the 2ndary,, the series switch
is different, On or bypass, primary is On/off..


have a 3rd light a primary too.. short lead.

put Schmidt's Edelux LED light on .. it's what i got this winter, for my commuter..
