I have lights, but after an hour of intermittent use, the batteries dim significantly. I need lights because I usually start my ride before 4am. It often doesn't get light enough to go without lights until about 5:30am. By then, my lights are kaput. Today, I noticed that even when I would turn them off when I wasn't using them, they still were dim by 5:15am, which sucked. I had a hard time seeing after that until the sun went up.
Does anyone have suggestions for long lasting lights that are at least 12 watts that I can easily affix to my handlebars and are preferably rechargeable? I'm going to Performance tomorrow for the members only sale, so I'll be stocking up then.
