Something to consider....
One thing to consider about LED's, aftermarket lights in general - many come with only one wire (as opposed to the 2 wire system on SilverToy) using the screw mount as ground. Might not be big deal, but then there has to be a good reason it was done with 2 wires the first time around.
Then again I did a clearance light swap with lights from LEDS-R-US and they do look great. Were about $5 or so a piece. Seems I remember they had tear drop shape as well. They do have a good web site so you could check there.
Hope that helps.
