This is a mod that I'd been planning on doing for a while, and finally got around to doing it when I realized I didn't have any solder paste around for a different headlight mod I was planning on doing...
I've got a PB Superflash, which is a really nice blinky, but it has waterproofing issues, and after seeing how easy it is to modify a PT EOS, and how they have much better waterproofing, I decided to pick up one of the older, now very cheap, PT EOS headlamps and a red-orange LED from ledsupply.com
There's lots of threads on these mods, so I won't bother to talk about it much - just to introduce the idea of putting a colored LED into a PT EOS to get a waterproof bike light. Based on the spec sheets, this light should put out around 40 lumens - pretty good for a taillight.
Here's the new LED soldered in, alongside the older Luxeon.
The new star on the motherboard. The new LED has thicker PCB, and the original optic holder doesn't seem to fit over the new star. I ended up just using some electrical tape to hold the optic (without the holder) in place. Once you put the light module back into the casing, it is kept in place by the casing and front cover lens.
The new PT EOS taillight on the left, and a PB Superflash set for steady light on the right. The PT EOS has a wider beam angle, and more light overall. It should be visible from a broader angle, and some people claim that a steady beam is a lot less irritating than a blinky. With the EOS tailight, you have 3 light levels to work with as well as a blink mode.
The optic looks like a carclo, so maybe I'll pick up an elliptical optic and put that in - it should be a lot more appropriate for a taillight.
