As the topic: why solar road markers must not be changeable design?

Simple but very pivotal:
1. Cost too expensive,
—because the product itself very expensive, so you need to make it re-useable, but if the unit products cost is very low. Why need to consider this case?!
—beside the product unit cost, the human cost will be much more expensive.
2. Working on the road is very dangerous,
—Every year, 1 person of 100 from the world died when working on the road. Especially in the developing country, it reaches 1.8%.  Terrible!
3. Why changeable design products are not durable?
—If you make one products changeable, you must split into several parts, and then assemble it. But this is the major reason for not durable.

If you doing trading, you may not understand well about what i say, but if you are doing projects, you should agree well with me. 🙂

Years before, when i was 1 of 4 people working on the road installing a marker, while i was watching a car flied over some warning cones, rolling one of my partners. Fortunately, this damaged one of his foot.

I was lucky, but i know i have the responsibility to do something.

Then i made my design,

1/10 cost of standard designs, much more durable
