They're pulse driven to give multiple brightness levels. Low as markers,
then they get bright when the brakes are activated. It has nothing to do
with increasing the max brightness.

There are auto parts stores in the USA that sell "drop-in" replacement
led lamps,. Murray's auto parts is one store in the Chicago suburbs
that I know my son-in-law has purchased them from (to dangle a
preposition).
