Dear customer, I understand your query, the intelligent lighting system it is possible to install it but the truth is not recommended in terms of costs, these systems require several components that can be highly expensive:
new adaptive headlights with intelligent pixel LED
configurable light points.
Intelligent light sensors.
In addition to the system of modules and chips, adding the whole installation which is somewhat tedious to perform, and this may be that its cost is a little high. but if it is possible to do the installation, in terms of costs, I have not really evaluated how much this type of work can cost but I know that they are somewhat high around 2k.
in terms of eliminating or adding the speed limit, all vehicles not only the Mercedes, have a speed limiter, which is easy to eliminate but this obviously is not done in authorized dealers or garages. There is a equipment very similar to a scanner, which is used only to condemn these retainers or speed limiters, this work is not expensive and does not require a long time to do it. it is simply like a configuration that is made to the vehicles to eliminate this limiter.
Have you understood dear customer?
