I'm not sure, but I believe that in TX M3W's are considered motorcycles, as they only have three wheels...
I ride motorcycles and I too try to stay as visible as I can be. On my main bike, an '09 Harley CVO Road Glide, I have installed a headlight modulator which takes the headlights and varies the voltage from 100% down to around 50% and then back, repeating continuously. I have a photo cell that I mounted under the front of the fairing so when it gets dusk out, the photo cell turns the modulator off. This is the law.
Also the law is that these headlight modulators, on motorcycles, is 50 state legal.
I've had cars in the fast lane pull over thinking I was a cop... They work great.
Then on the rear I have a Backoff Module. This modulates the brake light or third brake light in a series of repeating flashing patterns. On mine I hit the brakes and the brake light comes on for a few seconds and then it flashes four times and then repeats with a long and then repeated flashes. This is constant as long as I keep the brakes applied.
They are both very noticeable to the drivers around me. But being stuck at a light in front of another stopped car and that car being rear ended and subsequently you getting nailed.
Click Here For Modulators I also agree with getting a light of some sort up higher into the line of sight of the car behind you. I believe that a third brake light could be nicely mounted between the two roll bar hoops. A modulator on this would also be my choice.
I've also installed LED headlights and taillights on a couple of my motorcycles and they do a LOT to get attention. In the day time I always ride with my high beam on. I get a few flashes, but at least they see me.
Good luck and I hope you have more time to enjoy your M3W again.
