Truckers and USPS seem to love those retrofit kits. Almost all the
little Grumman postal vans and 40' commercial trailers I have seen
recently have them, with mounting rings looking newer that the rest of
the vehicle. Makes sense- for people on a schedule, a deadlined vehicle
due to a burned out bulb costs a lot more than the 1-time cost of the
changeover to LEDs, which basically should outlive the vehicle. Just
program the changeover in whenever the next scheduled service is. I
presume they are factory installed on any built in the last few years.
