I ordered the Dual Star
flashing LED tail light today. It's made for the KLR650 but it's a direct fit for many other bikes (I have one on my Bonneville America too).
I measured the KLX tail light internals last night and it should be no problem.
This unit is expensive but it's the brightest and most noticable I've ever seen on a bike. Way better than those cheapo replacement LED bulb clusters.
I get many positive comments from my riding buds on this unit. It's a small price to pay for not getting rear ended at a traffic light. Plus it saves watts!
The Pelican 1200 I ordered will be delivered tomorrow...Hmm...mounting options to consider...
