This V16 emergency light allows us not to have to leave the vehicle to signal, because you only have to install the light on the roof of the car by opening the window. It is activated automatically as soon as it is magnetically attached to the ceiling. Is a yellow car light, which provides a visibility over a kilometer. The battery that it has should last a year and a half, and the autonomy is about two and a half hours in emergency mode. Its price is around 20 euros and it is a perfect and essential purchase to increase safety when driving.
Is it mandatory? Since this 2021 it will be mandatory to have light or triangles. Previously they were complementary options. Now we can forget about the triangles. However, until 2024 the process of passing the triangles to light will take place. Even so, taking into account the price it has, and that it increases safety when traveling with the vehicle, and knowing that at some point we will have to acquire it, it is not a bad idea not to put it off too long.
When choosing, you have different options. One of the best known is Help Flash, designed by two former civil guards, and one of the first to have approval.
But it is not the only one. Something cheaper and with very fast shipping is this Motorkit light. It is also approved and is exactly the same on a technical level.
Good options to be prepared for any emergency and adapt to the new regulations that land in 2021.
