LED tail light are not "very bright". The illumination is very poor.

However LED lights are very focused and play on the human vision
system to compete with the effectiveness of incandescents.

Many incandescent tail lights have taken a lesson in efficiency also
and many of the so-called LED taillights on vehicles are actually
incandescent bulbs. Take a closer look and you will see many peanut
bulbs in a reflector with small pockets.

When will we see back-up LED lights on vehicles? Not likely in the
near future. The total luminence is not there to illuminate an area.
Something LEDs have failed at, to date.

I've seen LED back up lights on a couple of newer Luxury cars.
BTW, The 2009 Cadillac Escalade Platinum has LED headlights.

The only problem with high output LED lights is the need for cooling.
Like most semiconductor technologies, excessive heat will damage them.
The Cadillac LED headlights have built in cooling fans.
