Just received some nice cheap LED lights from Amazon (took only 2 days). They have 5 LEDs, and they are bright, but work really well. I ordered the Red ones, and the white ones, since for some odd reason, the yellow ones were more expensive. They were about $1.00 a piece for the Red and for the White. However, the yellow were $2.50 a piece oddly enough. I am very happy with the red, but the white made the yellow lenses a canary yellow, instead of the normal amber look. People may like that look, but I've found the replacement teardrops for my 64 are made of a very thin aluminum and the plastic lens doesn't fit evenly, so I'll need to seal the edges with silicone, which will leave a white light along the edge - hence I went ahead and ordered the amber LED.
