headlights for my revo..

[jokerjustin]

im trying to set up some leds to run in my revo... at my local bashing spot there is decent lighting but in some landing zones it gets a bit dark and i lose track of my truck.. i was trying to find somthing that would work off my 3rd channel in the radio so its easily turned off without the need for a switch... i would like them to be as bright as possible without dimishing my runtime...
plus i have a 20$ gift card from the local radio shack so i would like to use it.

i was looking at these since they are the highest intensity ive found..

but my prob is that the max voltage of them is 4v.. and im not positive but i think the mmm puts out 4.8? whats a good way to set this up?

i want it to be as small of a setup so its easily hidden
