I was looking for some replacement leds for my audleys taillights
and I found some 600mcd red leds for fairly cheap
I brought them home it says to operate them on 2.85V so I hooked it up to 2 aa batteries
these are the brightest leds I have ever seen
one of these 3mm leds would be more then enough for underglow on a bit
It would be best if it were mounted sticking out of the bottem of the middle of the chasse
as it is now my car has brighter taillights then headlights which can light up a room in any levels of darkness
