Last week I ordered a new headlight which is 1200 Lumen and has a 4400Mah rechargeable pack.
While I was at the light upgrades I added two Blackburn Mars Click Red rear Taillights one to each handlebar upright for additional 180º protection.
I have also added an additional Brake light called the Maxxon Wireless Brake light which is an addition to the one I already have. This light use an accelerometer to turn the light on when braking.
I also purchased the Cygolite HotShot 2W USB flashing taillight. This beauty can be charged from my computer and is truly bright.
This season has been an expensive one, new tires for the front and rear, a new Garmin Edge 500 with separate speed and cadence sensors. Next season I will try to replace the seat and cushion and neckrest.
