The eletronic flasher module that needs to be installed to run LED light properly, can also run the filament bulbs just fine.
The LED tail light with built in turn signals is not DOT, and is not safe to use alone. It cannot be readily seen in direct sunlight and will not get a drivers attention if they are distracted. I bought the same tail light off eBay that has only the tail and brake light (no turn signals), and it can be bought with either a clear or red lens....buy the one that matches your paint color best. Then install a supplemental brake light under the seat where the RYCA seat pan stops. Any one of these can be set to the non-flashing setting and used for a brake light...and they can be combined with the led pulse module that flashes the light 3 times and then burns steady if you want even more attention.

I then bought some very small turn signals with filament bulbs, and they were not much better as they used small bulbs and did not have any reflectors. I made them work well by installing a pair of 1.5 watt LED light heads in each turn signal. There are a lot of small turn signals out there that are sport bike takeoffs on eBay that are cheap, would be seen easily, and would be great turn signals with just a little bit of work to get them mounted. If you do buy LED turns signals....get bright ones.
Typical sport bike turn signal that might work really well if the mount can be adapted. The sport bike guys remove their rear fenders and turn signals right away. These are DOT approved and would work well.
