I have one of the LED lights from one of the web vendors (I think it was
superbrightled.com or something like that).  I bought a super bright red
one that even had LEDs pointed out around the circumference.  As there
is no true white LED, I figured a red one in a red lense would be bright.

It is not as bright as a stock brake light.  It is comparable to a
driving light, maybe a little brighter, but not enough for me to spend
the extra $$.  So I used it in one of the driving lights and did not buy
any more.

I will tell you that if you want to make your lights brighter, simply
buy new bulbs - this really made my other lights bright - so bright that
the turn signal lenses look transparent instead of orange.
