I’m in the process of swapping the driver in my MT07S over to a Lexel driver, and I’m stuck at working out what the connections on the original haikelite driver mean.

Picture of the existing driver connections

On the Lexel driver I have G (Ground), S (Switch), and L and LS for the switch LED’s.

On the original driver I have:

K1 – red wire
K2 –
R – white wire with pen marks
G – white wire
K- – black wire

First light with anything more complex in it that a clicky switch.

Would this be right?

S – red wire
G – black wire
L – White wire
LS – White wire with pen marks
