Lights

I bit the bullet and got a Light and Motion Stella 150L.
A very nifty little unit and bloody bright and doesn't look like a brick strapped to the bars. It works really well on the Cornish Lanes even in lowest setting. I will get to test the Retinas of London road users this week, but more than confident it will do the job.
Will try and post some pics at night as it's much better than i expected.

Very nice lights indeed all round. External battery packs though. Only reason I went for Dinottes over Stellas was due to no branding and clever mounting system.

They're sure to steer you well.
