Unfortunately, TX state law requires the minimum sensitivity to detect a motorcycle. Fortunately, I haven't found a sensor that won't detect a bicycle but will pick up a friend's Honda Rebel 500. Find somebody with a 500 or smaller, document the light not detecting that, contact TXDOT, wait a week or two while they either make excuses or ignore you, then forward copies of all correspondence to your state Rep with a handwritten note explaining that you can't get them to bring the lights into compliance with TC544.0075.
Typed letters and emails to Reps tend to get form replies from staffers. Handwritten notes tend to get handwritten replies from the actual Rep. I send mine something anytime I feel bad about my handwriting; his scrawl takes a few guesses to figure out which way is right side up, but at least I know he actually read my letter
