Can’t advise on installation of the flashing lights, sorry.
I bought it at an independent store on the ground floor of Big C in Nittayo Road, Udon Thani. I had looked elsewhere but this particular shop stocked a very good selection of trikes.
There were 3 versions of the X6-3: 500w, 600w plus the version I bought, 700w. It has 3 forward gears and reverse, disc brakes, full set of lights, and indicators, built in alarm and masses of storage space.
The 600w version @ 16,900฿ was attractive but on the day I went to buy, the more potent-looking 700w had appeared. I was able to test both models and the 700w had a more comfortable seat (the 600w sloped back), which was wider and upright. Important for me.
In 1st gear it reaches 28kph (17.4mph), in 2nd 38kph (23.6mph), and in 3rd 48kph (29.8mph).
It’s a great vehicle, I looked around for a year before finding this one.
I too am in my seventies (mid).
