You have countless choices, but I like the Baja Designs stuff if you are sticking with stalk mount signals.
Here's the Baja Designs rear turn signal.
If you also have a CycleRack, you can lay your TW on its side without breaking the turn signals.
Edit: I just checked the Baja Designs website, and at $33.00 a pair, I would think Hodaka Guy's modification of the stock turn signals seems to be the best bet.
Be carful with aftermarket turn signals. Many lack luminosity to meet the required visibility. Most states require the signals be bright enough to be seen from 500 feet away in daylight. Many tiny aftermarket units and LED conversions are not bright enough to be legal.

Does anyone know where you could find the pictures?I'm looking for Hodakaguy's method for shortening the stock rear turn signals. The photos are dead links.
Thanks Fred. That's my exact plan is to replace stock signals with 1157 and 1156 LED bulbs - as well as the tail light and indicators. And thanks for the buying guidance. I've been exploring options at superbrightleds.com but will take a look at other options.One can also simply replace the incandescent 1156 & 1157 bulbs with LED 1156 & 1157 bulbs. Like the incandescents the LEDs are usually available with various lumens output; I recommend searching a bit and selecting the brightest available. Many US resellers carry older inventory so newest technology and better prices can often be found on eBay and Amazon.
