I wanted brighter turn signals and some way to light a campsite without discharging my battery, and I achieved these objectives for about $25.
I bought this product, called LS-104 at an Auto Parts store:
For about $22 I got two units with 6 white LEDs in each, plus some hardware and a switch I don't need. Short red and black wires exit the middle of each unit. Here are the unmodified units:
I opened the cases and removed the short wires, then installed 6-foot two-wire cables that exit via new holes at the end of each unit. I checked the operation of the units, then glued them shut, sealing the original holes.
I glued these units to the bottom edge of my handguards, with the wires running inward, letting the trailing edge protrude about 5mm behind the trailing edge of each handguard. I used Gorilla glue, which is adequate but messy. Try to find a better glue for this if you do it.
I bought a 12-volt rechargeable battery at a yard sale. It is about 24cm x 8cm x 3 cm, weighs about 600 grams, holds a charge reasonably well, and powers a little TV for a couple of hours. I installed this on the bike's right flank, in a little cavity inside the right rear piece of tupperware. This auxiliary battery is not really necessary, but I prefer to power the LEDs with this instead of the bike's main battery.
Here is the schematic of my auxiliary battery and LED modules:
If you don't want to bother with an auxiliary battery, just ignore the connection to the taillight wire, omit the resistor and diode, and wire from your battery through a fuse to the DPDT switch (left side in the diagram).
The wire to the tailight is the brown wire in the cable that runs along the left side of my 2006 Wee-Strom, and perhaps the same on your Strom. I used the black-and-white wire in the same cable as ground.
Following the schematic, I ran wires from the front turn signals to one end of a DPDT toggle switch, and a wire from the auxiliary battery's positive terminal to the other end of the switch. I wired the positive connection of the LED modules to the middle of the switch. Thus, in one position the LEDs are in parallel with the front turn signals, and in the other position the LEDs are always on, powered by the auxiliary battery.
I left the bike off, with the LEDs on for ten hours, and they were still bright. The auxiliary battery's voltage fell from 13.2 to 12.3 in that time.
The LED modules have a third use. When I ride with the LED modules on, they augment the headlights and give a distinctive appearance to my bike - you will know when Colorado is the Strom in your mirrors.

I am very pleased with these LED modules, and I believe they will assist me when I have to set up camp after nightfall. I will be glad to answer questions and provide more photos. Right now the switch is installed poorly, and the wires are a tad sloppy, but I will correct those flaws next week.
Colorado is the name of my Wee-Strom. It came with a VIN ending 1876, the year Colorado became the Centennial State, and it is red, so the name is obviously correct. I certainly enjoyed riding this motorcycle in Colorado, and perhaps the motorcycle enjoyed that fine state as well.
