well l.e.d.s shine in a form of a projectile not like regular bulbs. so if you dont aim it right through the plastic piece in the back, it will not shine as bright or shine at all for the needles. i used 2 6 volt batteries to test how the shine was coming through, then i mounted them in place with shrink wrap.
again...the white bubs are stock, blues are l.e.d.s, and the needles all shine as bright as the speedo/rpm. the camera made the other two shine much brighter.
