I haven't tried them myself, as my cars already have LED tail and
brake lights. My greatest experience is in use of LED's to replace
interior lights in yachts, as well as Navigation lights, which have
very strict requirements set by the government. They have to be
visible for a specified distance, and in specific arcs of coverage,
both vertical and horizontal. They need to have full brightness in the
specified coverage parameters. Obviously single LED's won't do that,
which seems to completely stymie Josepi. The simple answer is that
most LED replacements for incandesent bulbs in almost ANY application
other than indicator lights on a panel,  are accomplished by use of
arrays of LED's, not a single LED.
