I just took my lights out today and amconsidering similar upgrades and enhancements (something to keep me busy in long winter nights :) ). I am, however, considering a LED setup. I got my hands on some unbelievably bright off-white (kinda little blueish) LEDs and am thinking to get them in, probably three. The other alternative is a bicycle white led light that even comes with the blinkong (or not, depending on the switch setting) circuit.
However, before I start icing I have to make the cake first, i.e. clean up the lenses and get better high/low bulbs. Does anyone know a non-agressive way to open these bug-eye lights?
